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.
hndiBind
Value of wParam. Identifies the NDI object that is to be unbound from this NDI object.
wBindType
Value of the low-order word of lParam. Specifies which edge of the NDI that hndiBind is to be added to.
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.
