Also, fixed * the copyright. * 03-23-90 GJF Made static functions _CALLTYPE4. * 07-23-90 SBM Compiles cleanly with -W3 (removed unreferenced * variable) * 08-13-90 SBM Compiles cleanly with -W3 with new build of compiler * 10-04-90 GJF New-style function declarators. * 01-22-91 GJF ANSI naming. * 08-15-91 MRM Calls tzset() to set timezone info in case of %z. * 08-16-91 MRM Put appropriate header file for tzset(). * 10-10-91 ETC Locale support under _INTL switch. * 12-18-91 ETC Use localized time strings structure. * 02-10-93 CFW Ported to Cuda tree, change _CALLTYPE4 to _CRTAPI3. * 02-16-93 CFW Massive changes: bug fixes & enhancements. * 03-08-93 CFW Changed _expand to _expandtime. * 03-09-93 CFW Handle string literals inside format strings. * 03-09-93 CFW Alternate form cleanup. * 03-17-93 CFW Change *count > 0, to *count != 0, *count is unsigned. * 03-22-93 CFW Change "C" locale time format specifier to 24-hour. * 03-30-93 GJF Call _tzset instead of __tzset (which no longer * exists). * 04-06-93 SKS Replace _CRTAPI* with __cdecl * 04-14-93 CFW Disable _alternate_form for 'X' specifier, fix count bug. * 04-28-93 CFW Fix bug in '%c' handling. * 07-15-93 GJF Call __tzset() in place of _tzset(). * 09-15-93 CFW Use ANSI conformant "__" names. * 04-11-94 GJF Made definitions of __lc_time_c, _alternate_form and * _no_lead_zeros conditional on ndef DLL_FOR_WIN32S. * 09-06-94 CFW Remove _INTL switch. * 02-13-95 GJF Appended Mac version of source file (somewhat cleaned * up), with appropriate #ifdef-s. * 09-26-95 GJF New locking macro, and scheme, for functions which * reference the locale. * 02-22-96 JWM Merge in PlumHall mods. * 06-17-96 SKS Enable new Plum-Hall code for _MAC as well as _WIN32 * 07-10-97 GJF Made __lc_time_c selectany. Also, removed unnecessary * init to 0 for globals, cleaned up the formatting a bit, * added a few __cdecls and detailed old (and no longer * used as of 6/17/96 change) Mac version. * 08-21-97 GJF Added support for AM/PM type suffix to time string. * 09-10-98 GJF Added support for per-thread locale info. * 03-04-99 GJF Added refcount field to __lc_time_c. * 05-17-99 PML Remove all Macintosh support. * 08-30-99 PML Don't overflow buffer on leadbyte in _store_winword. * 03-17-00 PML Corrected _Gettnames to also copy ww_timefmt (VS7#9374) * 09-07-00 PML Remove dependency on libcp.lib/xlocinfo.h (vs7#159463) * 03-25-01 PML Use GetDateFormat/GetTimeFormat in _store_winword for * calendar types other than the basic type 1, localized * Gregorian (vs7#196892) Also fix formatting for leading * zero suppression in fields, which was busted for %c, * %x, %X. * *******************************************************************************/ #include #include #include #include #include #include #include #include #include #include #include /* Prototypes for local routines */ static void __cdecl _expandtime( #ifdef _MT pthreadlocinfo ptloci, #endif char specifier, const struct tm *tmptr, char **out, size_t *count, struct __lc_time_data *lc_time, unsigned alternate_form);
