WMEMCHR(P)                                                          WMEMCHR(P)



NAME
       wmemchr - find a wide character in memory

SYNOPSIS
       #include <wchar.h>

       wchar_t *wmemchr(const wchar_t *ws, wchar_t wc, size_t n);


DESCRIPTION
       The  wmemchr()  function  shall  locate the first occurrence of wc in the initial 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 char-
       acter 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 func-
       tion behaves as if no valid occurrence of wc is found.

RETURN VALUE
       The wmemchr() function shall return a pointer to the located wide character,  or  a
       null pointer if the wide character does not occur in the object.

ERRORS
       No errors are defined.
