Standard C Library Functions wcsftime(3C)
NAME
wcsftime - convert date and time to wide character string
SYNOPSIS
#include
XPG4 and SUS
sizet wcsftime(wchart *wcs, sizet maxsize, const char *format,
const struct tm *timptr);
Default and other standards
sizet wcsftime(wchart *restrict wcs, sizet maxsize,
const wchart *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 gen-
erated 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, wcsftime() returns the number of wide-
character codes placed into the array pointed to by wcs,
not including the terminating null wide-character code. Oth-
erwise, 0 is returned and the contents of the array are
indeterminate.

Standard C Library Functions wcsftime(3C)
The wcfstime() function uses malloc(3C) and should malloc()
fail, errno will be set by malloc().

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