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, wcsftime() 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 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.
