wcsftime(3C) Standard C Library Functions wcsftime(3C)NAMEwcsftime - 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:
· The argument wcs points to the initial element of an array of
wide-characters into which the generated output is to be placed.
· The argument maxsize indicates the maximum number of wide-charac‐
ters to be placed in the output array.
· The argument format is a wide-character string and the conversion
specifications are replaced by corresponding sequences of wide-
characters.
· 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-char‐
acter 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 applica‐
tions, as long as setlocale(3C) is not being called to change the
locale.
