wcsstr - locate a substring in a wide-character string
#include <wchar.h>
wchar_t* wcsstr (const wchar_t* haystack, const wchar_t* needle);
The
wcsstr function is the wide-character equivalent of the strstr function.
It searches for the first occurrence of the wide-character string needle
(without its terminating L'\0' character) as a substring in the wide-character
string haystack.
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.
