NDI_QUERY_BIND
hndiBind = (HNDI)wParam; // handle of NDI object
wBindType = LOWORD(lParam); // type of binding
The NDI manager sends NDI_QUERY_BIND to inform the driver installer that an upper or lower binding is about to be added by NdiBind. The NDI_QUERY_BIND is sent before NdiBind returns.
Value | Meaning |
NDIBIND_UPPER | Specifies that the given NDI object should validate that hndiBind can be added to its upper bindings. |
NDIBIND_LOWER | Specifies that the given NDI object should validate that hndiBind can be added to its lower bindings. |
A driver installer that handles this message must also call NdiDefProc to perform standard bindings checking.
