NAME
wcsstr - find a wide-character substring
SYNOPSIS

#include <wchar.h>

wchar_t *wcsstr(const wchar_t *restrict ws1, const wchar_t *restrict ws2);
"ISO C++"

#include <wchar.h>

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

#include <cwchar>

wchar_t *std::wcsstr(wchar_t *ws1, const wchar_t *ws2);
DESCRIPTION

The wcsstr() function locates the first occurrence in the wide-character string pointed to by ws1 of the sequence of wide-characters (excluding the terminating null wide-character) in the wide-character string pointed to by ws2.

RETURN VALUES

On successful completion, wcsstr() returns 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 returns ws1.
