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. ATTRIBUTES
