WCSSTR

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.
