PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-

       Linux.

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.
