wcsftime: převést datum a čas na řetězec se širokými znaky

Originální popis anglicky: wcsftime - convert date and time to a wide-character string

Návod, kniha: POSIX Programmer's Manual

STRUČNĚ

#include <wchar.h>
 
 
size_t wcsftime(wchar_t *restrict wcs, size_t maxsize,
 
       const wchar_t *restrict format, const struct tm *restrict timeptr);
 

POPIS / INSTRUKCE

The wcsftime() function shall be equivalent to the strftime() 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 characters 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.

NÁVRATOVÁ HODNOTA

If the total number of resulting wide-character codes including the terminating null wide-character code is no more than maxsize, wcsftime() shall return the number of wide-character codes placed into the array pointed to by wcs, not including the terminating null wide-character code. Otherwise, zero is returned and the contents of the array are unspecified.
