wmemset(3posix)


NAME

   wmemset --- set wide characters in memory

SYNOPSIS

   #include <wchar.h>

   wchar_t *wmemset(wchar_t *ws, wchar_t wc, size_t n);

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  wmemset()  function  shall  copy  the value of wc into each of the
   first n wide characters of the object pointed to by ws.  This  function
   shall not be affected by locale and all wchar_t values shall be treated
   identically.  The  null  wide  character   and   wchar_t   values   not
   corresponding to valid characters shall not be treated specially.

   If  n is zero, the application shall ensure that ws is a valid pointer,
   and the function shall copy zero wide characters.

RETURN VALUE

   The wmemset() functions shall return the value of ws.
