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).
