WCSFTIME(3P)              POSIX Programmer's Manual             WCSFTIME(3P)

PROLOG         top

       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior), or
       the interface may not be implemented on Linux.

NAME         top

       wcsftime — convert date and time to a wide-character string

SYNOPSIS         top

       #include <wchar.h>

       size_t wcsftime(wchar_t *restrict wcs, size_t maxsize,
           const wchar_t *restrict format, const struct tm *restrict timeptr);

DESCRIPTION         top

       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.1‐2008 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.

        *  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 VALUE         top

       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.
