wcsstr - find a wide-character substring
#include <wchar.h> wchar_t *wcsstr(const wchar_t *restrict ws1, const wchar_t *restrict ws2);
#include <wchar.h> const wchar_t *wcsstr(const wchar_t *ws1, const wchar_t *ws2);
#include <cwchar> wchar_t *std::wcsstr(wchar_t *ws1, const wchar_t *ws2);
The wcsstr() function locates the first occurrence in the wide-character string pointed to by ws1 of the sequence of wide-characters (excluding the terminating null wide-character) in the wide-character string pointed to by ws2.
On successful completion, wcsstr() returns a pointer to the located wide-character string, or a null pointer if the wide-character string is not found.
If ws2 points to a wide-character string with zero length, the function returns ws1.
No errors are defined.
