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.
