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).
