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 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 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.
