WCSSTR(3) Linux Programmer's Manual WCSSTR(3)NAMEwcsstr - 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 nee‐
dle 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

The wcsstr() function is thread-safe.
