SYNOPSIS

#include <wchar.h>

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

DESCRIPTION

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.

The wcsstr() function shall locate 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 VALUE

Upon successful completion, wcsstr() 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.
