NAME

wcsstr - locate a substring in a wide-character string  

SYNOPSIS

#include <wchar.h>

wchar_t *wcsstr(const wchar_t *haystack, const wchar_t *needle);
 

DESCRIPTION

The wcsstr() function is the wide-character equivalent of the strstr(3) function. It searches for the first occurrence of the wide-character string needle (without its terminating null wide character (L'\0')) as a substring in the wide-character string haystack.  

RETURN VALUE

The wcsstr() function returns a pointer to the first occurrence of needle in haystack. It returns NULL if needle does not occur as a substring in haystack.

Note the special case: If needle is the empty wide-character string, the return value is always haystack itself.
