1997-03-08 05:30 Ulrich Drepper <drepper@cygnus.com> * argp/Makefile (routines): Add argp-eexst. * argp/argp-ba.c (argp_program_bug_address): Make `const'. * argp/argp-eexst.c: New file. Define exit status variable. * argp/argp-help.c (__argp_state_help): Use argp_err_exit_status variable instead of always exiting with value 1. * argp/argp-pv.c (argp_program_version): Make `const'. * argp/argp.h: Declare argp_err_exit_status. Patches by Miles Bader <miles@gnu.ai.mit.edu>. * locale/programs/localedef.c: Use argp_err_exit_status to terminate with correct value. * inet/rcmd.c (iruserok): Use euidaccess instead of half-hearted switching of UID before opening .rhosts. * libio/vsnprintf.c: Change implementation to follow ISO C 9X proposal. The return value now is always the number of characters which would be written if enough space is available. * manual/stdio.texi: Update description for new behaviour. * locale/locale.h (__locale_t): Don't use __locale_t for struct name and pointer to struct since old gccs cannot keep the namespaces apart. Rename struct to __locale_struct. * locale/duplocale.h: Likewise. * locale/newlocale.h: Likewise. * math/Makefile (headers): Add complex.h and cmathcalls.h. (routines): Remove w_cabs. Add conj, cimag, creal, and cabs. * math/math.h: Undefine __MATHDECL_1, __MATHDECL, and __MATHCALL after use. (signgam): Move declaration to here from mathcalls.h. * math/mathcalls.h (cabs, __cabs_complex, signgam): Remove definition. Correct comment for fmin and fmax. Start implementing complex math function from ISO C 9X. * math/complex.h: New file. * math/cmathcalls.h: New file. * math/cabs.c: New file. * math/cabsf.c: New file. * math/cabsl.c: New file. * math/cimag.c: New file. * math/cimagf.c: New file. * math/cimagl.c: New file. * math/conj.c: New file. * math/conjf.c: New file. * math/conjl.c: New file. * math/creal.c: New file. * math/crealf.c: New file. * math/creall.c: New file. * sysdeps/libm-ieee754/w_cabs.c: Removed. * sysdeps/libm-ieee754/w_cabsf.c: Removed. * sysdeps/libm-ieee754/w_cabsl.c: Removed. * posix/regex.c: Merge with regex sources from Arnold Robbins' version in GNU awk. * posix/regex.h: Likewise.

+ This file provides prototype declarations for the math functions.
+ Most functions are declared using the macro:
+
+ __MATHCALL (NAME, (ARGS...));
+
+ This means there is a function `NAME' returning `double' and a function
+ `NAMEf' returning `float'. Each place `_Mdouble_' appears in the
+ prototype, that is actually `double' in the prototype for `NAME' and
+ `float' in the prototype for `NAMEf'. Reentrant variant functions are
+ called `NAME_r' and `NAMEf_r'.
+
+ Functions returning other types like `int' are declared using the macro:
+
+ __MATHDECL (TYPE, NAME, (ARGS...));
+
+ This is just like __MATHCALL but for a function returning `TYPE'
+ instead of `_Mdouble_'. In all of these cases, there is still
+ both a `NAME' and a `NAMEf' that takes `float' arguments. */
