wcsftime(3C)             Standard C Library Functions             wcsftime(3C)

NAME
       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, ex‐
       cept 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  con‐
                  version  specifications  are  replaced  by corresponding se‐
                  quences 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-character
       code.  Otherwise, 0 is returned and the contents of the array are inde‐
       terminate.


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