Your Callback Function
You can define a callback function that NetSprocket will call for various asynchronous events. You do not need to define a callback function unless you plan to use certain advanced features of NetSprocket.
typedef pascal void (*NSpCallbackProcPtr) (
	NSpGameReference inGame,
	void *inContext,
	NSpEventCode inCode,
	OSStatus inStatus,
	void* inCookie);
inGame
An opaque reference to the game object making the callback.
inContext
A pointer that you passed in to the installation function.
inCode
A value describing what kind of event is being passed to your generic callback function when the callback is made.
inStatus
A status code containing noErr, a NetSprocket error, or an Open Transport error.
inCookie
A pointer that may be NULL or point to certain extra data for certain kinds of events.

DESCRIPTION
NetSprocket 1.0 does not make any generic asynchronous callbacks.
