        <<wcspbrk>>----scan wide-character string for a wide-character code

ANSI_SYNOPSIS

        #include <wchar.h>

        wchar_t *wcspbrk(const wchar_t *<[s]>, const wchar_t *<[set]>);

TRAD_SYNOPSIS

        wchar_t *wcspbrk(<[s]>, <[set]>

        const wchar_t *<[s]>;

        const wchar_t *<[set]>;

DESCRIPTION

        The <<wcspbrk>> function locates the first occurrence in the

        wide-character string pointed to by <[s]> of any wide-character code

        from the wide-character string pointed to by <[set]>.

RETURNS

        Upon successful completion, <<wcspbrk>> returns a pointer to the

        wide-character code or a null pointer if no wide-character code from

        <[set]> occurs in <[s]>.
