GPD_READEVENT -- Return the next game port event.
Read game port events from the game port and put them in the
data area of the iORequest. If there are no pending game port
events, this command will not be satisfied, but if there are
some events, but not as many as can fill IO_LENGTH, the
request will be satisfied with those currently available.
IO REQUEST
io_Message mn_ReplyPort set if quick I/O is not possible
io_Device preset by the call to OpenDevice
io_Unit preset by the call to OpenDevice
io_Command GPD_READEVENT
io_Flags IOB_QUICK set if quick I/O is possible
io_Length the size of the io_Data area in bytes: there
are sizeof(inputEvent) bytes per input event.
io_Data a buffer area to fill with input events. The
fields of the input event are:
ie_NextEvent
links the events returned
ie_Class
is IECLASS_RAWMOUSE
ie_SubClass
is 0 for the left, 1 for the right game port
ie_Code
contains any gameport button reports. No
report is indicated by the value 0xff.
ie_Qualifier
only the relative and button bits are set
ie_X, ie_Y
the x and y values for this report, in either
relative or absolute device dependent units.
ie_TimeStamp
the delta time since the last report, given
not as a standard timestamp, but as the frame
count in the TV_SECS field.
This function sets the error field in the iORequest, and fills
the iORequest with the next game port events (but not partial
events).
