PLAYBACK RELATED EVENTS

I find the following event relative to the XAPlayItf interface:
#define XA_PLAYEVENT_HEADATEND ((XAuint32) 0x00000001)
#define XA_PLAYEVENT_HEADATMARKER ((XAuint32) 0x00000002)
#define XA_PLAYEVENT_HEADATNEWPOS ((XAuint32) 0x00000004)
#define XA_PLAYEVENT_HEADMOVING ((XAuint32) 0x00000008)
#define XA_PLAYEVENT_HEADSTALLED ((XAuint32) 0x00000010)

Now I want to know when the OpenMAX AL will send the event to the application; in other words, what event will be sent when the following operation occurs: play, seek, pause,resume, stop.
