If the macro `_XOPEN_SOURCE' has the value 500 this includes all
functionality described so far plus some new definitions from the
Single Unix specification, version 2.
- Macro: _LARGEFILE_SOURCE
If this macro is defined some extra functions are available which
rectify a few shortcomings in all previous standards. More
concreten the functions `fseeko' and `ftello' are available.
Without these functions the difference between the ISO C interface
(`fseek', `ftell') and the low-level POSIX interface (`lseek')
would lead to problems.
This macro was introduced as part of the Large File Support
extension (LFS).
- Variable: Macro _LARGEFILE64_SOURCE
If you define this macro an additional set of function gets
available which enables to use on 32 bit systems to use files of
sizes beyond the usual limit of 2GB. This interface is not
available if the system does not support files that large. On
systems where the natural file size limit is greater than 2GB
(i.e., on 64 bit systems) the new functions are identical to the
replaced functions.
The new functionality is made available by a new set of types and
functions which replace existing. The names of these new objects
contain `64' to indicate the intention, e.g., `off_t' vs.
`off64_t' and `fseeko' vs. `fseeko64'.
This macro was introduced as part of the Large File Support
extension (LFS). It is a transition interface for the time 64 bit
offsets are not generally used (see `_FILE_OFFSET_BITS'.
- Variable: _FILE_OFFSET_BITS
This macro lets decide which file system interface shall be used,
one replacing the other. While `_LARGEFILE64_SOURCE' makes the
64 bit interface available as an additional interface
`_FILE_OFFSET_BITS' allows to use the 64 bit interface to replace
the old interface.
If `_FILE_OFFSET_BITS' is undefined or if it is defined to the
value `32' nothing changes. The 32 bit interface is used and
types like `off_t' have a size of 32 bits on 32 bit systems.
If the macro is defined to the value `64' the large file interface
replaces the old interface. I.e., the functions are not made
available under different names as `_LARGEFILE64_SOURCE' does.
Instead the old function names now reference the new functions,
e.g., a call to `fseeko' now indeed calls `fseeko64'.
This macro should only be selected if the system provides
mechanisms for handling large files. On 64 bit systems this macro
has no effect since the `*64' functions are identical to the
normal functions.
This macro was introduced as part of the Large File Support
extension (LFS).

sqrt (creal (@var{z}) * creal (@var{z}) + cimag (@var{z}) * cimag (@var{z}))

This function should always be used instead of the direct formula since
using the simple straight-forward method can mean to loose accuracy. If
one of the squared values is neglectable in size compared to the other
value the result should be the same as the larger value. But squaring
the value and afterwards using the square root function leads to
unaccuracy. See @code{hypot} in @xref{Exponents and Logarithms}.

@defvar Macro _LARGEFILE64_SOURCE
If you define this macro an additional set of function gets available
which enables to use on @w{32 bit} systems to use files of sizes beyond
the usual limit of 2GB. This interface is not available if the system
does not support files that large. On systems where the natural file
size limit is greater than 2GB (i.e., on @w{64 bit} systems) the new
functions are identical to the replaced functions.
The new functionality is made available by a new set of types and
functions which replace existing. The names of these new objects
contain @code{64} to indicate the intention, e.g., @code{off_t}
vs. @code{off64_t} and @code{fseeko} vs. @code{fseeko64}.
This macro was introduced as part of the Large File Support extension
(LFS). It is a transition interface for the time @w{64 bit} offsets are

@defvar _FILE_OFFSET_BITS
This macro lets decide which file system interface shall be used, one
replacing the other. While @code{_LARGEFILE64_SOURCE} makes the @w{64
bit} interface available as an additional interface
@code{_FILE_OFFSET_BITS} allows to use the @w{64 bit} interface to
replace the old interface.
If @code{_FILE_OFFSET_BITS} is undefined or if it is defined to the
value @code{32} nothing changes. The @w{32 bit} interface is used and
types like @code{off_t} have a size of @w{32 bits} on @w{32 bit}
systems.
If the macro is defined to the value @code{64} the large file interface
replaces the old interface. I.e., the functions are not made available
under different names as @code{_LARGEFILE64_SOURCE} does. Instead the
old function names now reference the new functions, e.g., a call to
@code{fseeko} now indeed calls @code{fseeko64}.
This macro should only be selected if the system provides mechanisms for
handling large files. On @w{64 bit} systems this macro has no effect
since the @code{*64} functions are identical to the normal functions.

@node Truncating Files
@section Change the size of a file
In some situations it is useful to explicitly determine the size of a
file. Since the 4.2BSD days there is a function to truncate a file to
at most a given number of bytes and POSIX defines one additional
function. The prototypes for these functions are in @file{unistd.h}.
@comment unistd.h
@comment X/Open
@deftypefun int truncate (const char *@var{name}, size_t @var{length})
The @code{truncation} function truncates the file named by @var{name} to
at most @var{length} bytes. I.e., if the file was larger before the
extra bytes are stripped of. If the file was small or equal to
@var{length} in size before nothing is done. The file must be writable
by the user to perform this operation.
The return value is zero is everything wnet ok. Otherwise the return
value is @math{-1} and the global variable @var{errno} is set to:
@table @code
@item EACCES
The file is not accessible to the user.
@item EINVAL
The @var{length} value is illegal.
@item EISDIR
The object named by @var{name} is a directory.
@item ENOENT
The file named by @var{name} does not exist.
@item ENOTDIR
One part of the @var{name} is not a directory.
@end table
This function was introduced in 4.2BSD but also was available in later
@w{System V} systems. It is not added to POSIX since the authors felt
it is only of marginally additional utility. See below.
@end deftypefun
@comment unistd.h
@comment POSIX
@deftypefun int ftruncate (int @var{fd}, size_t @var{length})
The @code{ftruncate} function is similar to the @code{truncate}
function. The main difference is that it takes a descriptor for an
opened file instead of a file name to identify the object. The file
must be opened for writing to successfully carry out the operation.
The POSIX standard leaves it implementation defined what happens if the
specified new @var{length} of the file is bigger than the original size.
The @code{ftruncate} function might simply leave the file alone and do
nothing or it can increase the size to the desired size. In this later
case the extended area should be zero-filled. So using @code{ftruncate}
is no reliable way to increase the file size but if it is possible it is
probably the fastest way. The function also operates on POSIX shared
memory segments if these are implemented by the system.
On success the function returns zero. Otherwise it returns @math{-1}
and set @var{errno} to one of these values:
@table @code
@item EBADF
@var{fd} is no valid file descriptor or is not opened for writing.
@item EINVAL
The object referred to by @var{fd} does not permit this operation.
@item EROFS

@node Synchronizing I/O
@section Synchronizing I/O operations
@cindex synchronizing
In most modern operation systems the normal I/O operations are not
executed synchronously. I.e., even if a @code{write} system call
returns this does not mean the data is actually written to the media,
e.g., the disk.
In situations where synchronization points are necessary the user can
use special functions which ensure that all operations finished before
they return.

@deftypefun int sync (void)
A call to this function will not return as long as there is data which
