broader definition; it can refer for example to a system's kernel, an
editor macro, a complex package of software, or a discrete section of
code executing within a process.
Writing the program is what this manual is all about. This chapter
explains the most basic interface between your program and the system
that runs, or calls, it. This includes passing of parameters (arguments
and environment) from the system, requesting basic services from the
system, and telling the system the program is done.
A program starts another program with the @code{exec} family of system calls.
This chapter looks at program startup from the execee's point of view. To
see the event from the execor's point of view, see @ref{Executing a File}.

In @w{ISO C} you can define @code{main} either to take no arguments, or to
1995-02-18 01:27:10 +00:00
take two arguments that represent the command line arguments to the
program, like this:
@smallexample
int main (int @var{argc}, char *@var{argv}[])
@end smallexample
@cindex argc (program argument count)
@cindex argv (program argument vector)
The command line arguments are the whitespace-separated tokens given in
the shell command used to invoke the program; thus, in @samp{cat foo
bar}, the arguments are @samp{foo} and @samp{bar}. The only way a
program can look at its command line arguments is via the arguments of
@code{main}. If @code{main} doesn't take arguments, then you cannot get
at the command line.
The value of the @var{argc} argument is the number of command line
arguments. The @var{argv} argument is a vector of C strings; its
elements are the individual command line argument strings. The file
name of the program being run is also included in the vector as the
first element; the value of @var{argc} counts this element. A null
pointer always follows the last element: @code{@var{argv}[@var{argc}]}
is this null pointer.
For the command @samp{cat foo bar}, @var{argc} is 3 and @var{argv} has
three elements, @code{"cat"}, @code{"foo"} and @code{"bar"}.
In Unix systems you can define @code{main} a third way, using three arguments:
@smallexample
int main (int @var{argc}, char *@var{argv}[], char *@var{envp}[])
1995-02-18 01:27:10 +00:00
@end smallexample
The first two arguments are just the same. The third argument

@var{envp} gives the program's environment; it is the same as the value
1995-02-18 01:27:10 +00:00
of @code{environ}. @xref{Environment Variables}. POSIX.1 does not
allow this three-argument form, so to be portable it is best to write
@code{main} to take two arguments, and use the value of @code{environ}.

Multiple options may follow a hyphen delimiter in a single token if
the options do not take arguments. Thus, @samp{-abc} is equivalent to
@samp{-a -b -c}.

@item
Certain options require an argument. For example, the @samp{-o} command
of the @code{ld} command requires an argument---an output file name.
@item
An option and its argument may or may not appear as separate tokens. (In
other words, the whitespace separating them is optional.) Thus,
@w{@samp{-o foo}} and @samp{-ofoo} are equivalent.
@item
Options typically precede other non-option arguments.
The implementations of @code{getopt} and @code{argp_parse} in @theglibc{}
normally make it appear as if all the option arguments were
1997-06-05 11:28:54 +00:00
specified before all the non-option arguments for the purposes of
parsing, even if the user of your program intermixed option and
non-option arguments. They do this by reordering the elements of the
@var{argv} array. This behavior is nonstandard; if you want to suppress
it, define the @code{_POSIX_OPTION_ORDER} environment variable.
@xref{Standard Environment}.
1995-02-18 01:27:10 +00:00
@item
The argument @samp{--} terminates all options; any following arguments
are treated as non-option arguments, even if they begin with a hyphen.
@item
A token consisting of a single hyphen character is interpreted as an
ordinary non-option argument. By convention, it is used to specify
input from or output to the standard input and output streams.
@item
Options may be supplied in any order, or appear multiple times. The
interpretation is left up to the particular application program.
@end itemize
@cindex long-named options
GNU adds @dfn{long options} to these conventions. Long options consist
of @samp{--} followed by a name made of alphanumeric characters and
dashes. Option names are typically one to three words long, with
hyphens to separate words. Users can abbreviate the option names as
long as the abbreviations are unique.
To specify an argument for a long option, write
@samp{--@var{name}=@var{value}}. This syntax enables a long option to
accept an argument that is itself optional.
Eventually, @gnusystems{} will provide completion for long option names

in the shell.

If the syntax for the command line arguments to your program is simple
enough, you can simply pick the arguments off from @var{argv} by hand.
But unless your program takes a fixed number of arguments, or all of the
arguments are interpreted in the same way (as file names, for example),
you are usually better off using @code{getopt} (@pxref{Getopt}) or
@code{argp_parse} (@pxref{Argp}) to do the parsing.

@code{getopt} is more standard (the short-option only version of it is a
part of the POSIX standard), but using @code{argp_parse} is often
easier, both for very simple and very complex option structures, because
it does more of the dirty work for you.

Having a single level of options is sometimes not enough. There might
be too many options which have to be available or a set of options is
closely related.
For this case some programs use suboptions. One of the most prominent
programs is certainly @code{mount}(8). The @code{-o} option take one
argument which itself is a comma separated list of options. To ease the
programming of code like this the function @code{getsubopt} is
available.

manual: Replace summary.awk with summary.pl. The Summary is now generated from @standards, and syntax-checking is performed. If invalid @standards syntax is detected, summary.pl will fail, reporting all errors. Failure and error reporting is disabled for now, however, since much of the manual is still incomplete wrt. header and standards annotations. Note that the sorting order of the Summary has changed; summary.pl respects the locale, like summary.awk did, but the use of LC_ALL=C is introduced in the Makefile. Other notable deviations are improved detection of the annotated elements' names, which are used for sorting, and improved detection of the @node used to reference into the manual. The most noticeable difference in the rendered Summary is that entries may now contain multiple lines, one for each header and standard combination. summary.pl accepts a `--help' option, which details the expected syntax of @standards.

1996-07-14 06:04:09 +00:00
The @var{tokens} parameter references an array of strings containing the
known suboptions. All strings must be @samp{\0} terminated and to mark
the end a null pointer must be stored. When @code{getsubopt} finds a
possible legal suboption it compares it with all strings available in
the @var{tokens} array and returns the index in the string as the
indicator.
In case the suboption has an associated value introduced by a @samp{=}
character, a pointer to the value is returned in @var{valuep}. The
string is @samp{\0} terminated. If no argument is available
@var{valuep} is set to the null pointer. By doing this the caller can
check whether a necessary value is given or whether no unexpected value
is present.
In case the next suboption in the string is not mentioned in the
@var{tokens} array the starting address of the suboption including a
possible value is returned in @var{valuep} and the return value of the
function is @samp{-1}.

@section Environment Variables
@cindex environment variable
When a program is executed, it receives information about the context in
which it was invoked in two ways. The first mechanism uses the
@var{argv} and @var{argc} arguments to its @code{main} function, and is
discussed in @ref{Program Arguments}. The second mechanism uses
@dfn{environment variables} and is discussed in this section.
The @var{argv} mechanism is typically used to pass command-line
arguments specific to the particular program being invoked. The
environment, on the other hand, keeps track of information that is
shared by many programs, changes infrequently, and that is less
frequently used.
The environment variables discussed in this section are the same
environment variables that you set using assignments and the
@code{export} command in the shell. Programs executed from the shell
inherit all of the environment variables from the shell.
@c !!! xref to right part of bash manual when it exists
@cindex environment
Standard environment variables are used for information about the user's
home directory, terminal type, current locale, and so on; you can define
additional variables for other purposes. The set of all environment
variables that have values is collectively known as the
@dfn{environment}.
Names of environment variables are case-sensitive and must not contain
the character @samp{=}. System-defined environment variables are
invariably uppercase.
The values of environment variables can be anything that can be
represented as a string. A value must not contain an embedded null
character, since this is assumed to terminate the string.

This function is similar to @code{getenv}, but it returns a null
pointer if the environment is untrusted. This happens when the
program file has SUID or SGID bits set. General-purpose libraries
should always prefer this function over @code{getenv} to avoid
vulnerabilities if the library is referenced from a SUID/SGID program.

The @code{putenv} function adds or removes definitions from the environment.
If the @var{string} is of the form @samp{@var{name}=@var{value}}, the
definition is added to the environment. Otherwise, the @var{string} is
interpreted as the name of an environment variable, and any definition
for this variable in the environment is removed.
If the function is successful it returns @code{0}. Otherwise the return
value is nonzero and @code{errno} is set to indicate the error.
The difference to the @code{setenv} function is that the exact string
given as the parameter @var{string} is put into the environment. If the
user should change the string after the @code{putenv} call this will
reflect automatically in the environment. This also requires that
@var{string} not be an automatic variable whose scope is left before the
variable is removed from the environment. The same applies of course to
dynamically allocated variables which are freed later.
This function is part of the extended Unix interface. You should define
@var{_XOPEN_SOURCE} before including any header.

manual: Replace summary.awk with summary.pl. The Summary is now generated from @standards, and syntax-checking is performed. If invalid @standards syntax is detected, summary.pl will fail, reporting all errors. Failure and error reporting is disabled for now, however, since much of the manual is still incomplete wrt. header and standards annotations. Note that the sorting order of the Summary has changed; summary.pl respects the locale, like summary.awk did, but the use of LC_ALL=C is introduced in the Makefile. Other notable deviations are improved detection of the annotated elements' names, which are used for sorting, and improved detection of the @node used to reference into the manual. The most noticeable difference in the rendered Summary is that entries may now contain multiple lines, one for each header and standard combination. summary.pl accepts a `--help' option, which details the expected syntax of @standards. If errors are reported, the user is directed to this feature for further information. * manual/Makefile: Generate summary.texi with summary.pl. Force use of the C locale.

The @code{setenv} function can be used to add a new definition to the
environment. The entry with the name @var{name} is replaced by the
value @samp{@var{name}=@var{value}}. Please note that this is also true
if @var{value} is the empty string. To do this a new string is created
and the strings @var{name} and @var{value} are copied. A null pointer
for the @var{value} parameter is illegal. If the environment already
contains an entry with key @var{name} the @var{replace} parameter
controls the action. If replace is zero, nothing happens. Otherwise
the old entry is replaced by the new one.

manual: Replace summary.awk with summary.pl. The Summary is now generated from @standards, and syntax-checking is performed. If invalid @standards syntax is detected, summary.pl will fail, reporting all errors. Failure and error reporting is disabled for now, however, since much of the manual is still incomplete wrt. header and standards annotations. Note that the sorting order of the Summary has changed; summary.pl respects the locale, like summary.awk did, but the use of LC_ALL=C is introduced in the Makefile. Other notable deviations are improved detection of the annotated elements' names, which are used for sorting, and improved detection of the @node used to reference into the manual. The most noticeable difference in the rendered Summary is that entries may now contain multiple lines, one for each header and standard combination. summary.pl accepts a `--help' option, which details the expected syntax of @standards.

Using this function one can remove an entry completely from the
environment. If the environment contains an entry with the key
@var{name} this whole entry is removed. A call to this function is
equivalent to a call to @code{putenv} when the @var{value} part of the
string is empty.
The function returns @code{-1} if @var{name} is a null pointer, points to
an empty string, or points to a string containing a @code{=} character.
It returns @code{0} if the call succeeded.
This function was originally part of the BSD library but is now part of
the Unix standard. The BSD version had no return value, though.

function is said to be used in the POSIX.9 (POSIX bindings for Fortran

manual: Replace summary.awk with summary.pl. The Summary is now generated from @standards, and syntax-checking is performed. If invalid @standards syntax is detected, summary.pl will fail, reporting all errors. Failure and error reporting is disabled for now, however, since much of the manual is still incomplete wrt. header and standards annotations. Note that the sorting order of the Summary has changed; summary.pl respects the locale, like summary.awk did, but the use of LC_ALL=C is introduced in the Makefile. Other notable deviations are improved detection of the annotated elements' names, which are used for sorting, and improved detection of the @node used to reference into the manual. The most noticeable difference in the rendered Summary is that entries may now contain multiple lines, one for each header and standard combination. summary.pl accepts a `--help' option, which details the expected syntax of @standards. If errors are reported, the user is directed to this feature for further information. * manual/Makefile: Generate summary.texi with summary.pl. Force use of the C locale.

@standards{POSIX.1, unistd.h}
1995-02-18 01:27:10 +00:00
The environment is represented as an array of strings. Each string is
of the format @samp{@var{name}=@var{value}}. The order in which
strings appear in the environment is not significant, but the same
@var{name} must not appear more than once. The last element of the
array is a null pointer.
This variable is declared in the header file @file{unistd.h}.
If you just want to get the value of an environment variable, use

@cindex @code{HOME} environment variable
1995-02-18 01:27:10 +00:00
@cindex home directory
This is a string representing the user's @dfn{home directory}, or
initial default working directory.
The user can set @code{HOME} to any value.
If you need to make sure to obtain the proper home directory
for a particular user, you should not use @code{HOME}; instead,
look up the user's name in the user database (@pxref{User Database}).
For most purposes, it is better to use @code{HOME}, precisely because
this lets the user specify the value.

identify the user who is running a program; a function like
1995-02-18 01:27:10 +00:00
@code{getlogin} (@pxref{Who Logged In}) is better for that purpose.
For most purposes, it is better to use @code{LOGNAME}, precisely because
this lets the user specify the value.
@item PATH
@cindex @code{PATH} environment variable
1995-02-18 01:27:10 +00:00
A @dfn{path} is a sequence of directory names which is used for
searching for a file. The variable @code{PATH} holds a path used
for searching for programs to be run.
The @code{execlp} and @code{execvp} functions (@pxref{Executing a File})
use this environment variable, as do many shells and other utilities
which are implemented in terms of those functions.
The syntax of a path is a sequence of directory names separated by
colons. An empty string instead of a directory name stands for the
1995-02-18 01:27:10 +00:00
current directory (@pxref{Working Directory}).
A typical value for this environment variable might be a string like:
@smallexample
:/bin:/etc:/usr/bin:/usr/new/X11:/usr/new:/usr/local/bin
@end smallexample
This means that if the user tries to execute a program named @code{foo},
the system will look for files named @file{foo}, @file{/bin/foo},
@file{/etc/foo}, and so on. The first of these files that exists is
the one that is executed.
@c !!! also TERMCAP
@item TERM
@cindex @code{TERM} environment variable
1995-02-18 01:27:10 +00:00
This specifies the kind of terminal that is receiving program output.
Some programs can make use of this information to take advantage of
special escape sequences or terminal modes supported by particular kinds
of terminals. Many programs which use the termcap library
(@pxref{Finding a Terminal Description,Find,,termcap,The Termcap Library
Manual}) use the @code{TERM} environment variable, for example.
@item TZ
@cindex @code{TZ} environment variable
1995-02-18 01:27:10 +00:00
This specifies the time zone. @xref{TZ Variable}, for information about
the format of this string and how it is used.
@item LANG
@cindex @code{LANG} environment variable
1995-02-18 01:27:10 +00:00
This specifies the default locale to use for attribute categories where
neither @code{LC_ALL} nor the specific environment variable for that
category is set. @xref{Locales}, for more information about
locales.
@ignore
@c I doubt this really exists
@item LC_ALL
@cindex @code{LC_ALL} environment variable
1995-02-18 01:27:10 +00:00
This is similar to the @code{LANG} environment variable. However, its
value takes precedence over any values provided for the individual
attribute category environment variables, or for the @code{LANG}
environment variable.

When a program is executed, it receives information from the operating
system about the environment in which it is operating. The form of this
information is a table of key-value pairs, where the keys are from the
set of @samp{AT_} values in @file{elf.h}. Some of the data is provided
by the kernel for libc consumption, and may be obtained by ordinary
interfaces, such as @code{sysconf}. However, on a platform-by-platform
basis there may be information that is not available any other way.
@subsection Definition of @code{getauxval}
@deftypefun {unsigned long int} getauxval (unsigned long int @var{type})
manual: Replace summary.awk with summary.pl. The Summary is now generated from @standards, and syntax-checking is performed. If invalid @standards syntax is detected, summary.pl will fail, reporting all errors. Failure and error reporting is disabled for now, however, since much of the manual is still incomplete wrt. header and standards annotations. Note that the sorting order of the Summary has changed; summary.pl respects the locale, like summary.awk did, but the use of LC_ALL=C is introduced in the Makefile. Other notable deviations are improved detection of the annotated elements' names, which are used for sorting, and improved detection of the @node used to reference into the manual. The most noticeable difference in the rendered Summary is that entries may now contain multiple lines, one for each header and standard combination. summary.pl accepts a `--help' option, which details the expected syntax of @standards. If errors are reported, the user is directed to this feature for further information. * manual/Makefile: Generate summary.texi with summary.pl. Force use of the C locale. Update Perl dependency comment. * manual/header.texi: Update reference to summary.awk. * manual/macros.texi: Refer authors to `summary.pl --help'. * manual/summary.awk: Remove file. * manual/summary.pl: New file.

This function is used to inquire about the entries in the auxiliary
vector. The @var{type} argument should be one of the @samp{AT_} symbols
defined in @file{elf.h}. If a matching entry is found, the value is
returned; if the entry is not found, zero is returned and @code{errno} is
set to @code{ENOENT}.

For some platforms, the key @code{AT_HWCAP} is the easiest way to inquire
about any instruction set extensions available at runtime. In this case,
there will (of necessity) be a platform-specific set of @samp{HWCAP_}

@node System Calls
@section System Calls
@cindex system call
A system call is a request for service that a program makes of the
kernel. The service is generally something that only the kernel has
the privilege to do, such as doing I/O. Programmers don't normally
need to be concerned with system calls because there are functions in
@theglibc{} to do virtually everything that system calls do.

@cindex kernel call
System calls are sometimes called kernel calls.
However, there are times when you want to make a system call explicitly,
and for that, @theglibc{} provides the @code{syscall} function.

@code{syscall} probably won't accept anything less than kernel and C
library source code as a specification of the interface between them
anyway.
@code{syscall} is declared in @file{unistd.h}.
@deftypefun {long int} syscall (long int @var{sysno}, @dots{})
manual: Replace summary.awk with summary.pl. The Summary is now generated from @standards, and syntax-checking is performed. If invalid @standards syntax is detected, summary.pl will fail, reporting all errors. Failure and error reporting is disabled for now, however, since much of the manual is still incomplete wrt. header and standards annotations. Note that the sorting order of the Summary has changed; summary.pl respects the locale, like summary.awk did, but the use of LC_ALL=C is introduced in the Makefile. Other notable deviations are improved detection of the annotated elements' names, which are used for sorting, and improved detection of the @node used to reference into the manual. The most noticeable difference in the rendered Summary is that entries may now contain multiple lines, one for each header and standard combination. summary.pl accepts a `--help' option, which details the expected syntax of @standards. If errors are reported, the user is directed to this feature for further information. * manual/Makefile: Generate summary.texi with summary.pl. Force use of the C locale. Update Perl dependency comment. * manual/header.texi: Update reference to summary.awk. * manual/macros.texi: Refer authors to `summary.pl --help'. * manual/summary.awk: Remove file. * manual/summary.pl: New file.

@code{syscall} performs a generic system call.
@cindex system call number
@var{sysno} is the system call number. Each kind of system call is
identified by a number. Macros for all the possible system call numbers
are defined in @file{sys/syscall.h}
The remaining arguments are the arguments for the system call, in
order, and their meanings depend on the kind of system call. Each kind
of system call has a definite number of arguments, from zero to five.
If you code more arguments than the system call takes, the extra ones to
the right are ignored.
The return value is the return value from the system call, unless the
system call failed. In that case, @code{syscall} returns @code{-1} and
sets @code{errno} to an error code that the system call returned. Note
that system calls do not return @code{-1} when they succeed.
@cindex errno
If you specify an invalid @var{sysno}, @code{syscall} returns @code{-1}
with @code{errno} = @code{ENOSYS}.
Example:
@smallexample
#include <unistd.h>
#include <sys/syscall.h>
#include <errno.h>

@node Program Termination
@section Program Termination
@cindex program termination
@cindex process termination
@cindex exit status value
The usual way for a program to terminate is simply for its @code{main}
function to return. The @dfn{exit status value} returned from the
@code{main} function is used to report information back to the process's
parent process or shell.
A program can also terminate normally by calling the @code{exit}
function.
In addition, programs can be terminated by signals; this is discussed in
more detail in @ref{Signal Handling}. The @code{abort} function causes
a signal that kills the program.
@menu
* Normal Termination:: If a program calls @code{exit}, a
process terminates normally.

A process terminates normally when its program signals it is done by
calling @code{exit}. Returning from @code{main} is equivalent to
calling @code{exit}, and the value that @code{main} returns is used as
the argument to @code{exit}.

The @code{exit} function tells the system that the program is done, which
causes it to terminate the process.
@var{status} is the program's exit status, which becomes part of the
process' termination status. This function does not return.

@end deftypefun
Normal termination causes the following actions:
@enumerate
@item
1995-02-18 01:27:10 +00:00
Functions that were registered with the @code{atexit} or @code{on_exit}
functions are called in the reverse order of their registration. This
mechanism allows your application to specify its own ``cleanup'' actions
to be performed at program termination. Typically, this is used to do
things like saving program state information in a file, or unlocking
locks in shared data bases.
@item
1995-02-18 01:27:10 +00:00
All open streams are closed, writing out any buffered output data. See
@ref{Closing Streams}. In addition, temporary files opened
with the @code{tmpfile} function are removed; see @ref{Temporary Files}.
@item

@code{_exit} is called, terminating the program. @xref{Termination Internals}.
@end enumerate
@node Exit Status
@subsection Exit Status
@cindex exit status
When a program exits, it can return to the parent process a small
amount of information about the cause of termination, using the
@dfn{exit status}. This is a value between 0 and 255 that the exiting
process passes as an argument to @code{exit}.
Normally you should use the exit status to report very broad information
about success or failure. You can't provide a lot of detail about the
reasons for the failure, and most parent processes would not want much
detail anyway.
There are conventions for what sorts of status values certain programs
should return. The most common convention is simply 0 for success and 1
for failure. Programs that perform comparison use a different
convention: they use status 1 to indicate a mismatch, and status 2 to
indicate an inability to compare. Your program should follow an
existing convention if an existing convention makes sense for it.
A general convention reserves status values 128 and up for special
purposes. In particular, the value 128 is used to indicate failure to
execute another program in a subprocess. This convention is not
universally obeyed, but it is a good idea to follow it in your programs.
@strong{Warning:} Don't try to use the number of errors as the exit
status. This is actually not very useful; a parent process would
generally not care how many errors occurred. Worse than that, it does
not work, because the status value is truncated to eight bits.
Thus, if the program tried to report 256 errors, the parent would
receive a report of 0 errors---that is, success.
For the same reason, it does not work to use the value of @code{errno}
as the exit status---these can exceed 255.
@strong{Portability note:} Some non-POSIX systems use different
conventions for exit status values. For greater portability, you can
use the macros @code{EXIT_SUCCESS} and @code{EXIT_FAILURE} for the
conventional status value for success and failure, respectively. They
are declared in the file @file{stdlib.h}.

@node Cleanups on Exit
@subsection Cleanups on Exit
Your program can arrange to run its own cleanup functions if normal
termination happens. If you are writing a library for use in various
application programs, then it is unreliable to insist that all
applications call the library's cleanup functions explicitly before
exiting. It is much more robust to make the cleanup invisible to the
application, by setting up a cleanup function in the library itself
using @code{atexit} or @code{on_exit}.

A process exit status is saved to be reported back to the parent process
via @code{wait} or @code{waitpid}; see @ref{Process Completion}. If the
program exited, this status includes as its low-order 8 bits the program
exit status.

@item
Any child processes of the process being terminated are assigned a new
parent process. (On most systems, including GNU, this is the @code{init}
process, with process ID 1.)
@item
A @code{SIGCHLD} signal is sent to the parent process.
@item
If the process is a session leader that has a controlling terminal, then
a @code{SIGHUP} signal is sent to each process in the foreground job,
and the controlling terminal is disassociated from that session.
@xref{Job Control}.
@item
If termination of a process causes a process group to become orphaned,
and any member of that process group is stopped, then a @code{SIGHUP}
signal and a @code{SIGCONT} signal are sent to each process in the
group. @xref{Job Control}.
