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.
