From ccadf7b5346a3e21c692dfcbfcf38a63433bc36a Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 14 Mar 2004 21:12:06 +0000 Subject: Update. 2004-03-14 Ulrich Drepper Make the non-_l functions wrappers around the _l functions. * include/monetary.h: Declare __vstrmon_l. * include/string.h: Add libc_hidden_proto for __strcoll_l and __strxfrm_l. * include/time.h: Define ptime_locale_status. Declare __strptime_internal. * include/wchar.h: Add libc_hidden_proto for __wcscoll_l and __wcsxfrm_l. * stdlib/strfmon.c: Move the code to strfmon_l.c. Add little wrapper around __vstrfmon_l. * stdlib/strfmon_l.c: Add real implementation. Split into new function __vstrfmon_l to allow calling it from strfmon. * stdlib/strtod.c: Move real code to strtod_l.c and add wrapper. * stdlib/strtod_l.c: Add real implementation. * stdlib/strtof.c: Adjust to changed strtod.c. * stdlib/strtof_l.c: Include strtod_l.c now. * stdlib/strtold.c: New file. * stdlib/strtold_l.c: Removed. * string/strcoll.c: Move real code to strcoll_l.c: Add wrapper. * string/strcoll_l.c: Add real implementation. * string/strxfrm.c: Move real code to strxfrm_l.c: Add wrapper. * string/strxfrm_l.c: Add real implementation. * sysdeps/generic/strtol.c: Move real implementation to strtol_l.c. Add wrappers. * sysdeps/generic/strtol_l.c: Add real implementation. * sysdeps/generic/strtold.c: Removed. * sysdeps/generic/strtold_l.c: New file. * sysdeps/generic/strtoll_l.c: Include strtol_l.c now. Adjust #defines. * sysdeps/generic/strtoul_l.c: Likewise. * sysdeps/generic/strtoull_l.c: Likewise. * sysdeps/generic/wcstol_l.c: Likewise. * sysdeps/generic/wcstoll_l.c: Likewise. * sysdeps/generic/wcstoul_l.c: Likewise. * sysdeps/generic/wcstoull_l.c: Likewise. * sysdeps/ieee754/ldbl-128/strtold.c: Removed. * sysdeps/ieee754/ldbl-128/strtold_l.c: New file. * sysdeps/ieee754/ldbl-96/strtold.c: Removed. * sysdeps/ieee754/ldbl-96/strtold_l.c: New file. * sysdeps/m68k/strtold.c: Removed. * sysdeps/m68k/strtold_l.c: New file. * time/strftime.c: Move real code to strftime_l.c. Add wrapper. * time/strftime_l.c: Add real implementation. * time/strptime.c: Move real code to strptime_l.c. Add wrapper. * time/strptime_l.c: Add real implementation. * time/wcsftime.c: Simplify since only wrappers are defined in strftime.c. * time/wcsftime_l.c: Include strftime_l.c. * wcsmbs/wcscoll.c: Simplify since the file is not used by wcscoll_l.c anymore. * wcsmbs/wcscoll_l.c: Include strcoll_l.c. * wcsmbs/wcsxfrm.c: Simplify since the file is not used by wcsxfrm_l.c anymore. * wcsmbs/wcsxfrm_l.c: Include strxfrm_l.c. * wcsmbs/wcstod.c: Prepare to include new strtod.c. * wcsmbs/wcstod_l.c: Include strtod_l.c. * wcsmbs/wcstof.c: Prepare to include new strtof.c. * wcsmbs/wcstof_l.c: Include strtof_l.c. * wcsmbs/wcstold.c: Prepare to include new strtold.c. * wcsmbs/wcstold_l.c: Include strtold_l.c. * locale/uselocale.c: Use _NL_CURRENT_LOCALE instead of __libc_tsd_get. * sysdeps/generic/strcasecmp.c: Optimize a bit. It's better to get a reference to the current locale and then use the _l functions. * sysdeps/generic/strncase.c: Likewise. --- stdlib/strfmon.c | 632 +------------------------------------------------------ 1 file changed, 4 insertions(+), 628 deletions(-) (limited to 'stdlib/strfmon.c') diff --git a/stdlib/strfmon.c b/stdlib/strfmon.c index b17dc9823c..b11f95c9ac 100644 --- a/stdlib/strfmon.c +++ b/stdlib/strfmon.c @@ -19,645 +19,21 @@ Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA. */ -#include -#include -#include -#include #include -#ifdef USE_IN_LIBIO -# include "../libio/libioP.h" -# include "../libio/strfile.h" -#endif -#include #include -#include -#include -#include "../locale/localeinfo.h" +#include -#define out_char(Ch) \ - do { \ - if (dest >= s + maxsize - 1) \ - { \ - __set_errno (E2BIG); \ - va_end (ap); \ - return -1; \ - } \ - *dest++ = (Ch); \ - } while (0) - -#define out_string(String) \ - do { \ - const char *_s = (String); \ - while (*_s) \ - out_char (*_s++); \ - } while (0) - -#define out_nstring(String, N) \ - do { \ - int _n = (N); \ - const char *_s = (String); \ - while (_n-- > 0) \ - out_char (*_s++); \ - } while (0) - -#define to_digit(Ch) ((Ch) - '0') - - -/* We use this code also for the extended locale handling where the - function gets as an additional argument the locale which has to be - used.
