* strftime.c (strftime):
|
||||
When invoking self, check whether the subsidiary invocation failed.
|
||||
Use "???" (not "") to denote unknown time zone information.
|
||||
|
||||
Make this source file portable to standalone contexts (e.g. GNU Emacs).
|
||||
<config.h>: Include if HAVE_CONFIG_H is defined.
|
||||
(HAVE_LIMITS_H, HAVE_MBLEN, HAVE_TM_ZONE, STDC_HEADERS): New symbols,
|
||||
defined if _LIBC or if <config.h> defines them.
|
||||
<ansidecl.h>, "../locale/localeinfo.h": Include only if _LIBC.
|
||||
<sys/types.h>: New include; some hosts require it for `time_t'.
|
||||
<ctype.h>: Include only if HAVE_MBLEN (since it's only needed then).
|
||||
<limits.h>: Include only if HAVE_LIMITS_H.
|
||||
<stddef.h, stdlib.h, string.h>: Include only if STDC_HEADERS.
|
||||
(memcpy): Define in terms of bcopy if !STDC_HEADERS.
|
||||
(__P, PTR): Define if not already defined.
|
||||
(__tzname, __daylight, __timezone): Remove macros; no longer needed.
|
||||
(add, strftime): Don't use NULL, for portability to some weird hosts.
|
||||
(fmt): If !_LIBC, don't assume sprintf returns a count.
|
||||
(week, strftime): Use old-style function declarations.
|
||||
(weekday_name, month_name): New constants.
|
||||
(strftime): Use traditional C values if locale support isn't available.
|
||||
Use `const' instead of CONST. For time zones, use tm_zone if
|
||||
possible, then fall back on tzname. Don't check for multibyte
|
||||
characters unless mblen is supported. Use formats like %02d instead

of %.2d, for portability to older hosts.
