+FUNCTION
+	<<wmemchr>>---find a wide-character in memory
+ 
+
+ANSI_SYNOPSIS
+	#include <wchar.h>
+	wchar_t	*wmemchr(const wchar_t *<[s]>, wchar_t <[c]>, size_t <[n]>);
+
+TRAD_SYNOPSIS
+	wchar_t	*wmemchr(<[s]>, <[c]>, <[n]>
+	const wchar_t *<[s]>;
+	wchar_t <[c]>;
+	size_t <[n]>;
+
+DESCRIPTION
+	The <<wmemchr>> function locates the first occurrence of <[c]> in the
+	initial <[n]> wide-characters of the object pointed to be <[s]>. This
+	function is not affected by locale and all wchar_t values are treated
+	identically.  The null wide-character and wchar_t values not
+	corresponding to valid characters are not treated specially.
+
+	If <[n]> is zero, <[s]> must be a valid pointer and the function
+	behaves as if no valid occurrence of <[c]> is found. 
+
+RETURNS
+	The <<wmemchr>> function returns a pointer to the located
+	wide-character, or a null pointer if the wide-character does not occur
+	in the object. 
+
+PORTABILITY
+<<wmemchr>> is ISO/IEC 9899/AMD1:1995 (ISO C).
+No supporting OS subroutines are required.
