wcsftime(3posix)


NAME

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

SYNOPSIS

   #include <wchar.h>

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

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.12008
   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

   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.
