PROLOG

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

NAME

12       wcsftime - convert date and time to a wide-character string
13

SYNOPSIS

15       #include <wchar.h>
16
17       size_t wcsftime(wchar_t *restrict wcs, size_t maxsize,
18              const  wchar_t  *restrict  format,  const  struct  tm  *restrict
19       timeptr);

DESCRIPTION

23       The wcsftime() function shall be equivalent to the strftime() function,
24       except that:
25
26        * The argument wcs points to the initial element of an array  of  wide
27          characters into which the generated output is to be placed.
28
29        * The argument maxsize indicates the maximum number of wide characters
30          to be placed in the output array.
31
32        * The argument format is a wide-character string  and  the  conversion
33          specifications are replaced by corresponding sequences of wide char‐
34          acters.
35
36        * The return value indicates the number of wide characters  placed  in
37          the output array.
38
39       If  copying  takes  place between objects that overlap, the behavior is
40       undefined.
41

RETURN VALUE

43       If the total number of resulting  wide-character  codes  including  the
44       terminating  null  wide-character  code  is no more than maxsize, wcsf‐
45       time() shall return the number of wide-character codes placed into  the
46       array  pointed to by wcs, not including the terminating null wide-char‐
47       acter code. Otherwise, zero is returned and the contents of  the  array
48       are unspecified.
