From b8fe19fa809ac786b7d3dbb464cb1b3f887dc69d Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 22 May 1996 02:11:55 +0000 Subject: Wed May 22 01:48:54 1996 Ulrich Drepper * stdlib/strtol.c [!QUAD] (ULONG_MAX, LONG_MAX): Define these macros if they are not available. (WEAKNAME): New macro to declare argument as weak. Define function with __ prefix and add normal name as weak alias. * sysdeps/posix/euidaccess.c (S_IROTH, S_IWOTH, S_IXOTH): Defines these macros if not already available based on R_OK, W_OK, and X_OK. Tue May 21 18:48:46 1996 Roland McGrath * misc/sys/syslog.h (__need___va_list): Define this instead of __need_va_list before including . * Makerules (o-iterator): Use $(object-suffixes-left) instead of $(object-suffixes) to produce repetitions; this is used for other lists than just that one. [versioned]: Use $(o-iterator) properly. * sysdeps/unix/sysv/linux/Implies: Include `gnu'. * sysdeps/mach/hurd/Implies: Likewise. Sat May 18 02:57:46 1996 Ulrich Drepper * login/Makefile: New file. This directory contains functions for user administration. * Makefile (subdirs): Add login. * misc/Makefile (headers): Remove utmp.h. Now in login/utmp.h. (extra-libs, libutil-routines): Ditto. * misc/login.c, misc/login_tty.c, misc/logout.c, misc/logwtmp.c, misc/utmp.h: Moved to misc/. * login/login.c, login/login_tty.c, login/logout.c, login/logwtmp.c, login/utmp.h: Moved to here from misc/. * login/utmp.h: Split file. Definitions of data structures and constants are now in the system dependent utmpbits.h file. * login/setutent_r.c, login/setutent.c, login/endutent_r.c, login/endutent.c, login/getutent_r.c, login/getutent.c, login/getutid_r.c, login/getutid.c, login/getutline_r.c, login/getutline.c, login/pututline_r.c, login/pututline.c: New files. Routines to handle utmp-style files. * sysdeps/gnu/utmpbits.h: New file. Contains GNU/Linux specific definitions of utmp data structures and constants. * sysdeps/unix/sysv/utmpbits.h: Renamed from sysdeps/unix/sysv/utmp.h. * sysdeps/generic/utmpbits.h: New file. Generic (BSDish) version of definitions of utmp data structures and constants. Fri May 17 00:01:31 1996 Ulrich Drepper * locale/C-monetary.c: Default value for mon_decimal_point should be '.'. * stdio-common/printf.h: Remove Linux libc compatibility stuff. Add `extra' flag. Currently used in __printf_fp. * stdio-common/printf_fp.c (__guess_grouping): Renamed from `guess_grouping' and extend visibility to extern. This function is now used in `strfmon'. (__printf_fp): Recognize new bit flag in info struct. This triggers to use the grouping information and decimal point from the LC_MONETARY category instead of the LC_NUMERIC category. * stdio-common/vfprintf.c (process_arg): Correct major bug. In `complicated' loop we must not use the varargs because the args are already available in the ARGS_VALUE array. * stdlib/Makefile (headers): Add monetary.h. (routines): Add strfmon. * stdlib/monetary.h: New file. Header for strfmon function. * stdlib/strfmon.c: New file. Implement strfmon function to print monetary amounts according to current locale's rules. * sysdeps/unix/sysv/linux/i386/sys/vm86.h: The kernel header is now (>= Linux-1.3.100) called . --- manual/arith.texi | 22 ++++++++++++---------- 1 file changed, 12 insertions(+), 10 deletions(-) (limited to 'manual/arith.texi') diff --git a/manual/arith.texi b/manual/arith.texi index a5d2814b1d..b3f646a187 100644 --- a/manual/arith.texi +++ b/manual/arith.texi @@ -446,20 +446,20 @@ These functions are declared in @file{stdlib.h}. @deftypefun {long int} strtol (const char *@var{string}, char **@var{tailptr}, int @var{base}) The @code{strtol} (``string-to-long'') function converts the initial part of @var{string} to a signed integer, which is returned as a value -of type @code{long int}. +of type @code{long int}.
