MySetUpPort
Sets up the graphics port. This is how you would define your port setup function if you were to name it MySetUpPort:
void* MySetUpPort (JMFrameRef frame);
frame- The frame that wants the port.
- function result
- Defined by the client application. You can return any value depending on how you want to use the graphics port.
DISCUSSION
When creating a frame, you must designate a callback function to set up a graphics port (GrafPort) associated with it. You cannot nest this function.
