wcsstr

WCSSTR(3)						     Linux Programmer's Manual							 WCSSTR(3)

NAME

       wcsstr - locate a substring in a wide-character string

SYNOPSIS

       #include <wchar.h>

       wchar_t *wcsstr(const wchar_t *haystack, const wchar_t *needle);

DESCRIPTION

       The wcsstr() function is the wide-character equivalent of the strstr(3) function.  It searches for the first occurrence of the wide-charac-
       ter string needle (without its terminating null wide character (L'')) as a substring in the wide-character string haystack.

RETURN VALUE

       The wcsstr() function returns a pointer to the first occurrence of needle in haystack.  It returns NULL if needle does not occur as a  sub-
       string in haystack.

       Note the special case: If needle is the empty wide-character string, the return value is always haystack itself.
