DefNdiProc

RETERR CALLBACK DefNdiProc(hndi, uMsg, wParam, lParam)
HNDI hndi;    // NDI handle
UINT uMsg;    // message
WPARAM wParam;    // first message parameter
LPARAM lParam;    // second message parameter

The DefNdiProc is the default NDI procedure that processes messages sent to an NDI object. If an NDI object does not have a custom installer procedure, the default installer procedure will be used. If an NDI object has a custom NDI procedure, it should pass messages to DefNdiProc for default handling.

hndi

Identifies the NDI object.

uMsg

Specifies the message.

wParam

Specifies 16 bits of additional message-dependent information.

lParam

Specifies 32 bits of additional message-dependent information.

• The return value is zero (OK) if the message is not handled or is handled successfully. The return value is always an NDI-defined error value.
