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

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

SSYYNNOOPPSSIISS
       #include <wchar.h>

       size_t wcsftime(wchar_t *restrict _w_c_s, size_t _m_a_x_s_i_z_e,
           const wchar_t *restrict _f_o_r_m_a_t, const struct tm *restrict _t_i_m_e_p_t_r);

       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 _w_c_s_f_t_i_m_e() function shall be equivalent to the _s_t_r_f_t_i_m_e() function,
       except that:

        *  The argument _w_c_s points to the initial element of an array of wide
           characters into which the generated output is to be placed.

        *  The argument _m_a_x_s_i_z_e indicates the maximum number of wide
           characters to be placed in the output array.

        *  The argument _f_o_r_m_a_t 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.

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

       No errors are defined.
