+FUNCTION
+	<<wcschr>>---wide-character string scanning operation
+
+ANSI_SYNOPSIS
+	#include <wchar.h>
+	wchar_t *wcschr(const wchar_t *<[s]>, wchar_t <[c]>);
+
+TRAD_SYNOPSIS
+	wchar_t *wcschr(<[s]>, <[c]>
+	const wchar_t *<[s]>;
+	wchar_t <[c]>;
+
+DESCRIPTION
+	The <<wcschr>> function locates the first occurrence of <[c]> in the
+	wide-character string pointed to by <[s]>. The value of <[c]> must be a
+	character representable as a type wchar_t and must be a wide-character
+	code corresponding to a valid character in the current locale.
+	The terminating null wide-character string.
+
+RETURNS
+	Upon completion, <<wcschr>> returns a pointer to the wide-character
+	code, or a null pointer if the wide-character code is not found. 
+
+PORTABILITY
+<<wcschr>> is ISO/IEC 9899/AMD1:1995 (ISO C).
+No supporting OS subroutines are required.
