Имя (Name)
wcsftime — convert date and time to a wide-character string
Синопсис (Synopsis)
#include <wchar.h>
size_t wcsftime(wchar_t *restrict wcs, size_t maxsize,
const wchar_t *restrict format, const struct tm *restrict timeptr);
Описание (Description)
The functionality described on this reference page is aligned
with the ISO C standard. Any conflict between the requirements
described here and the ISO C standard is unintentional. This
volume of POSIX.1‐2017 defers to the ISO C standard.
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. It is unspecified whether an
encoding error occurs if the format string contains wchar_t
values that do not correspond to members of the character set
of the current locale.
* Field widths specify the number of wide characters instead of
the number of bytes.
* 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.
Возвращаемое значение (Return value)
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.
