|
|
||||||
.SH DESCRIPTION
|
|
||||||
The following description is transcribed verbatim from the December 7, 1988
|
|
||||||
draft standard for ANSI C.
|
|
||||||
This draft is essentially identical in technical content
|
|
||||||
to the final version of the standard.
|
|
||||||
.LP
|
|
||||||
The
|
|
||||||
.B strftime
|
|
||||||
function places characters into the array pointed to by
|
|
||||||
.B s
|
|
||||||
as controlled by the string pointed to by
|
|
||||||
.BR format .
|
|
||||||
The format shall be a multibyte character sequence, beginning and ending in
|
|
||||||
its initial shift state.
|
|
||||||
The
|
|
||||||
.B format
|
|
||||||
string consists of zero or more conversion specifiers and ordinary
|
|
||||||
multibyte characters. A conversion specifier consists of a
|
|
||||||
.B %
|
|
||||||
character followed by a character that determines the behavior of the
|
|
||||||
conversion specifier.
|
|
||||||
All ordinary multibyte characters (including the terminating null
|
|
||||||
character) are copied unchanged into the array.
|
|
||||||
If copying takes place between objects that overlap the behavior is undefined.
|
|
||||||
No more than
|
|
||||||
.B maxsize
|
|
||||||
characters are placed into the array.
|
|
||||||
Each conversion specifier is replaced by appropriate characters as described
|
|
||||||
in the following list.
|
|
||||||
The appropriate characters are determined by the
|
|
||||||
.B LC_TIME
|
|
||||||
category of the current locale and by the values contained in the
|
|
||||||
structure pointed to by
|
|
||||||
.BR timeptr .
|
|
||||||
.TP
|
|
||||||
.B %a
|
|
||||||
is replaced by the locale's abbreviated weekday name.
|
|
||||||

|
|
||||||
is replaced by the locale's full weekday name.
|
|
||||||
.TP
|
|
||||||
.B %b
|
|
||||||
is replaced by the locale's abbreviated month name.
|

|
|
||||||
.B %B
|
|
||||||
is replaced by the locale's full month name.
|
|
||||||
.TP
|
|
||||||

|
|
||||||
is replaced by the locale's appropriate date and time representation.
|
|
||||||
.TP
|
|
||||||
.B %d
|
|
||||||
is replaced by the day of the month as a decimal number
|
|
||||||
.RB ( 01 - 31 ).
|
|
||||||
.TP
|
|
||||||
.B %H
|
|
||||||
is replaced by the hour (24-hour clock) as a decimal number
|
|
||||||
.RB ( 00 - 23 ).
|
|
||||||
.TP
|
|
||||||
.B %I
|
|
||||||
is replaced by the hour (12-hour clock) as a decimal number
|
|

.RB ( 01 - 12 ).
|
|
||||||
.TP
|
|
||||||
.B %j
|
|
||||||

|
|
||||||
.TP
|
|
||||||
.B %m
|
|
||||||
is replaced by the month as a decimal number
|
|
||||||
.RB ( 01 - 12 ).

|
|
||||||
with a 12-hour clock.
|
|
||||||
.TP
|
|
||||||

|
|
||||||

|
|
||||||
.RB ( 00 - 53 ).
|
|
||||||
.TP
|
|
||||||
.B %x
|
|
||||||
is replaced by the locale's appropriate date representation.
|
|
||||||
.TP
|
|
||||||
.B %X
|
|
||||||
is replaced by the locale's appropriate time representation.
|
|
||||||
.TP
|
|
||||||
.B %y
|
|
||||||
is replaced by the year without century as a decimal number
|
|
||||||
.RB ( 00 - 99 ).
|
|
||||||
.TP
|
|
||||||
.B %Y
|
|
||||||
is replaced by the year with century as a decimal number.
|
|
||||||
.TP
|
|
||||||
.B %Z
|
|
||||||
is replaced by the time zone name or abbreviation, or by no characters if
|
|
||||||
no time zone is determinable.
|
|
||||||
.TP
|
|
||||||
.B %%
|
|
||||||
is replaced by
|
|
||||||
.BR % .
|
|
||||||
.LP
|
|
||||||
If a conversion specifier is not one of the above, the behavior is
|
|
||||||
undefined.
|
|
||||||
.SH RETURNS
|
|
||||||
If the total number of resulting characters including the terminating null
|
|
||||||
character is not more than
|
|
||||||
.BR maxsize ,
|
|
||||||
the
|
|
||||||
.B strftime

||||||
function returns the number of characters placed into the array pointed to
|
|
||||||
by
|
|
||||||
.B s
|
|
||||||
not including the terminating null character.
|
|
||||||
Otherwise, zero is returned and the contents of the array are indeterminate.

|
|
||||||
If
|
|
||||||
.B SYSV_EXT
|
|
||||||
is defined when the routine is compiled, then the following additional

.TP
|
|
||||||
.B %h
|
|

If
|
|
||||||
.B SUNOS_EXT
|
|
||||||
is defined when the routine is compiled, then the following additional
|
|
||||||
conversions will be available.
|
|
||||||
These are borrowed from the SunOS version of
|
|
||||||
.IR strftime .
|
|
||||||
.TP
|
|
||||||
.B %k
|
|
||||||
is replaced by the hour (24-hour clock) as a decimal number
|

||||||
and
|
|
||||||
.B SUNOS_EXT
|
|
||||||
are available, as well as the
|
|

.TP
|
|
||||||
.B %C
|
|
||||||
The century, as a number between 00 and 99.
|

is replaced by the week number of the year (the first Monday as the first
|
|
||||||
day of week 1) as a decimal number
|
|
||||||
.RB ( 01 - 53 ).
|
|
||||||
The method for determining the week number is as specified by ISO 8601
|
|
||||||
(to wit: if the week containing January 1 has four or more days in the
|
|
||||||
new year, then it is week 1, otherwise it is the highest numbered
|
|
||||||
week of the previous year (52 or 53)
|
|
||||||
and the next week is week 1).

.B %U
|
|
||||||
and

.B %W
|
|
||||||
this way:
|

is replaced by the week number of the year (the first Sunday as the first
|
|

day of week 1) as a decimal number
|
|

.RB ( 00 - 53 ).
|
|

All days in a new year preceding the first Sunday are considered to be
|
|
||||||
in week 0.
|
|

.B %W
|
|
||||||
is replaced by the week number of the year (the first Monday as the first

day of week 1) as a decimal number
|
|
||||||
.RB ( 00 - 53 ).
|

.B ISO_DATE_EXT
|
|
||||||
is defined, then all of the conversions available with
|
|
||||||
.BR POSIX2_DATE,
|
|
||||||
.BR SYSV_EXT,
|
|
||||||
and
|
|
||||||
.B SUNOS_EXT
|
|
||||||
are available, as well as the
|
|
||||||
following additional conversions:
|
|
||||||
.TP
|
|
||||||
.B %G
|
|
||||||
is replaced by the year with century of the ISO week number (see
|
|
||||||
.BR %V ,
|
|
||||||
above) as a decimal number.
|
|
||||||
.TP
|
|
||||||
.B %g
|
|
||||||
is replaced by the year without century of the ISO week number,
|
|
||||||
as a decimal number
|
|
||||||
.RB ( 00 - 99 ).
|
|
||||||
.PP
|
|
||||||
For example, January 1, 1993, is in week 53 of 1992. Thus, the year
|
|
||||||
of its ISO week number is 1992, even though its year is 1993.
|
|
||||||
Similarly, December 31, 1973, is in week 1 of 1974. Thus, the year
|
|
||||||
of its ISO week number is 1974, even though its year is 1973.

.SH BUGS
|
|
||||||
This version does not handle multibyte characters or pay attention to the
|
|
||||||
setting of the
|
|
||||||
.B LC_TIME
|
|
||||||
environment variable.
|
|
||||||
.LP
|
|
||||||
The ``appropriate'' values used for
|
|
||||||
.BR %c ,
|
|
||||||
.BR %x ,
|
|
||||||
are
|
|
||||||
.B %X
|
|
||||||
are those specified by the 1003.2 standard for the POSIX locale.
|
|
||||||
.SH CAVEATS
|
|
||||||
The pre-processor symbol
|
|
||||||
.B POSIX_SEMANTICS
|
|
||||||
is automatically defined, which forces the code to call
|
|
||||||
.IR tzset (3)
|
|
||||||
whenever the
|
|
||||||
.B TZ
|
|
||||||
environment variable has changed.
|
|
||||||
If this routine will be used in an application that will not be changing
|
|
||||||
.BR TZ ,
|
|
||||||
then there may be some performance improvements by not defining
|
|
||||||
.BR POSIX_SEMANTICS .

/*
|
|
||||||
* strftime.c
|
|
||||||
*
|
|
||||||
* Public-domain implementation of ANSI C library routine.
|
|
||||||
*
|
|
||||||
* It's written in old-style C for maximal portability.
|
|
||||||
* However, since I'm used to prototypes, I've included them too.
|
|
||||||
*
|
|
||||||
* If you want stuff in the System V ascftime routine, add the SYSV_EXT define.
|
|
||||||
* For extensions from SunOS, add SUNOS_EXT.
|
|
||||||
* For stuff needed to implement the P1003.2 date command, add POSIX2_DATE.
|
|
||||||
* For VMS dates, add VMS_EXT.
|
|
||||||
* For a an RFC822 time format, add MAILHEADER_EXT.
|
|
||||||
* For ISO week years, add ISO_DATE_EXT.
|
|
||||||
* For complete POSIX semantics, add POSIX_SEMANTICS.
|
|
||||||
*
|
|
||||||
* The code for %c, %x, and %X now follows the 1003.2 specification for
|
|
||||||
* the POSIX locale.
|
|
||||||
* This version ignores LOCALE information.
|
|
||||||
* It also doesn't worry about multi-byte characters.
|
|
||||||
* So there.
|
|
||||||
*
|
|
||||||
* This file is also shipped with GAWK (GNU Awk), gawk specific bits of
|
|
||||||
* code are included if GAWK is defined.

Hi Arnold,
|
|

in a process of fixing of strftime() in libraries on Atari ST I grabbed
|
|
||||||
some pieces of code from your own strftime. When doing that it came
|
|
||||||
to mind that your weeknumber() function compiles a little bit nicer
|
|
||||||
in the following form:

* tzset.c

*
|

* Quick and dirty emulation of tzset(), tzname[], and daylight
|

||||||
* for old BSD systems without it.
|
|
||||||
*
|
|
||||||
* Thanks to Rick Adams, rick@uunet.uu.net, for the basics.

*
|
|
||||||
* BUGS:
|
|
||||||
* Totally ignores the value of the TZ environment variable.
