WCSFTIME(3) BSD Library Functions Manual WCSFTIME(3)NAME
wcsftime, wcsftime_l -- convert date and time to a wide-character string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <wchar.h>
size_t
wcsftime(wchar_t *restrict wcs, size_t maxsize, const wchar_t *restrict format, const struct tm *restrict timeptr);
#include <wchar.h>
#include <xlocale.h>
size_t
wcsftime_l(wchar_t *restrict wcs, size_t maxsize, const wchar_t *restrict format, const struct tm *restrict timeptr, locale_t loc);
DESCRIPTION
The wcsftime() function is equivalent to the strftime() function, except for the types of its arguments. Refer to strftime(3) for a detailed
description.
While the wcsftime() function uses the current locale, the wcsftime_l() function may be passed a locale directly. See xlocale(3) for more
information.
COMPATIBILITY
Some early implementations of wcsftime() had a format argument with type const char *, instead of const wchar_t *.
SEE ALSO strftime(3), xlocale(3)STANDARDS
The wcsftime() function conforms to ISO/IEC 9899:1999 (``ISO C99'').

wcsftime - convert date and time to wide character string
SYNOPSIS
#include <wchar.h>
XPG4 and SUS
size_t wcsftime(wchar_t *wcs, size_t maxsize, const char *format,
const struct tm *timptr);
Default and other standards
size_t wcsftime(wchar_t *restrict wcs, size_t maxsize,
const wchar_t *restrict format,
const struct tm *restrict timptr);
DESCRIPTION
The wcsftime() function is equivalent to the strftime(3C) function, except that:
o The argument wcs points to the initial element of an array of wide-characters into which the generated output is to be placed.
o The argument maxsize indicates the maximum number of wide-characters to be placed in the output array.
o The argument format is a wide-character string and the conversion specifications are replaced by corresponding sequences of
wide-characters.
o The return value indicates the number of wide-characters placed in the output array.
If copying takes place between objects that overlap, the behavior is undefined.
RETURN VALUES
If the total number of resulting wide character codes (including the terminating null wide-character code) is no more than maxsize, wcsf-
time() returns the number of wide-character codes placed into the array pointed to by wcs, not including the terminating null wide-charac-
ter code. Otherwise, 0 is returned and the contents of the array are indeterminate.
The wcfstime() function uses malloc(3C) and should malloc() fail, errno will be set by malloc().

The wcsftime() function can be used safely in multithreaded applications, as long as setlocale(3C) is not being called to change the
locale.

Strange behaviour of the strftime() function from gawk (3.1.5):
$ awk 'BEGIN{print strftime("%T", 3600)}'
> 02:00:00
$ awk 'BEGIN{print strftime("%T", 0)}'
> 01:00:00
Obviously something with DST but I can not figure out why? To me 3600 epoch seconds remains 01:00, DST or not.

Hi,
I'm wrote a small program on HPUX that uses wcsftime, but this function seems to be not working - I get 0 as a result, the output buffer returns empty, and errno is 0 :
#include <iostream>
using namespace std;
int main ()
{
size_t formattedTimeLength = 0;
wchar_t formattedTime... (9 Replies)
HI,
i wish to convert a millsec value to a readable string format.
the one option is to use strftime.
However this is a bit costly (1-5 micros).
is there a a faster way to do so with just string manipulation
(Note i have the date object which has the time details but wish o avoid strftime) (2 Replies)
I frequently use awk time functions and am switching some scripts over to mawk. I don't have the mktime or strftime functions in mawk, but it appears that there is a way, as explained here in "Time functions":
Please only cut-and-past links to man pages from our man pages.
So, simple... (10 Replies)
