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(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.
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.
For an explanation of the terms used in this section, see
attributes(7).
