NDI_QUERY_BIND


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.

Meaning

NDIBIND_UPPER

A driver installer that handles this message must also call NdiDefProc to perform standard bindings checking.
