/*
FUNCTION
        <<wcschr>>---wide-character string scanning operation

SYNOPSIS
        #include <wchar.h>
        wchar_t *wcschr(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.
