Synopsis:

#include <OMXAL/OpenMAXAL_QNX.h>

struct XAQNXVideoBufferQueueSourceItf_ {
    XAresult (*RegisterCallback)(XAQNXVideoBufferQueueSourceItf self,
                                 xaQNXVideoBufferQueueSourceCallback callback,
                                 void *pCallbackContext);
} ;

Arguments:

self: A reference to the source interface
