Sparse issues an 'Using plain integer as NULL pointer' warning when passing the constant '0' as the second parameter in the call to the WSAEventSelect() function. The function parameter has a pointer type (WSAEVENT, aka HANDLE, aka void *) so that, in order to suppress the warning, we simply pass NULL for that parameter in the function call expression.
