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, 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().

NOTES

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