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-character
       string needle (without its terminating null wide character (L'\0')) 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
       substring in haystack.

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