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 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).
