|
||||
of many files which contained only symbol aliases, reducing the size of
|
||||
the source and the compiled library; many other files were renamed to
|
||||
less cryptic names previously occupied by the symbol alias files.
|
||||
There is a new header file <elf.h> and new library `-lelf' for
|
||||
programs which operate on files in the ELF format.
|
||||
|
||||
* Converted to Autoconf version 2, so `configure' has more options.
|
||||
Run `configure --help' to see the details.
|
||||
|
||||
* The library can now be configured to build profiling, highly-optimized
|
||||
(but undebuggable), and/or shared libraries (ELF with GNU ld only).
|
||||
The `--enable-profile', `--enable-omitfp', and `--enable-shared'
|
||||
options to `configure' enable building these extra libraries.
|
||||
The shared library is built by default when using both ELF and GNU ld.
|
||||
|
||||
* The new functions `strtoq' and `strtouq' parse integer values from
|
||||
strings, like `strtol' and `strtoul', but they return `long long int' and
|
||||
`unsigned long long int' values, respectively (64-bit quantities).
|
||||
|
||||
* The new functions `strtof' and `strtold' parse floating-point values from
|
||||
strings, like `strtod', but they return `float' and `long double' values,
|
||||
respectively (on some machines `double' and `long double' are the same).
|
||||
|
||||
* Ulrich Drepper has contributed new implementations of the floating-point
|
||||
printing and reading code used in the `printf' family of functions and
|
||||
`strtod', `strtof', and `strtold'. These new functions are perfectly
|
||||
accurate, and much faster than the old ones.
|
||||
|
||||
* The new header <langinfo.h> defines an interface for accessing
|
||||
various locale-dependent data (using the locale chosen with `setlocale').
|
||||
|
||||
* You can now use positional parameter specifications in format strings
|
||||
for the `printf' and `scanf' families of functions. For example,
|
||||
`printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
|
||||
``Number 6, Mr Jones''. This is mainly useful when providing different
|
||||
format strings for different languages, whose grammar may dictate
|
||||
a different ordering of the values being printed. To support this
|
||||
feature, the interface for `register_printf_handler' has changed; see
|
||||
the header file <printf.h>.
|
||||
|
||||
* The `printf' and `scanf' families of functions now understand a new
|
||||
formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
|
||||
to group numbers as indicated by the locale; for `scanf' and friends, this
|
||||
says to accept as valid only a number with all the proper grouping
|
||||
separators in the right places. In the default "C" locale, numbers are
|
||||
not grouped; but locales for specific countries will define the usual
|
||||
conventions (i.e. separate thousands with `,' in the US locale).
|
||||
|
||||
* The pgrp functions have been regularized, slightly incompatibly but much
|
||||
less confusingly. The core functions are now `getpgid' and `setpgid',

of a malloc'd block, given any address within the block. This can be
