wcsstr - locate a substring in a wide-character string

CONTENTS

Synopsis
Description

#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 function. It searches for the first occurrence of the wide-character string needle (without its terminating L’\0’ character) 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.

ISO/ANSI C, UNIX98

strstr(3), wcschr(3)
