       terminating null wide-character code.

RETURN VALUE

       The wcslen() function shall return the length of ws; no return value is reserved to indicate an error.

NAME

       wcswcs - find a wide substring (LEGACY)

SYNOPSIS

       #include <wchar.h>

       wchar_t *wcswcs(const wchar_t *ws1, const wchar_t *ws2);

DESCRIPTION

       The  wcswcs()  function	shall locate the first occurrence in the wide-character string pointed to by ws1 of the sequence of wide-character
       codes (excluding the terminating null wide-character code) in the wide-character string pointed to by ws2.

RETURN VALUE

       Upon successful completion, wcswcs() shall return a pointer to the located wide-character string or a null pointer  if  the  wide-character
       string is not found.

       If ws2 points to a wide-character string with zero length, the function shall return ws1.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       This  function  was not included in the final ISO/IEC 9899:1990/Amendment 1:1995 (E). Application developers are strongly encouraged to use
       the wcsstr() function instead.

RATIONALE

       None.

FUTURE DIRECTIONS

       This function may be withdrawn in a future version.
