trfc

The instance of an object that has the callback methods for tRFC handling. See this example:

class reg:

	def __init__(self):
		self.cnt = 0
		import os

...

	def TRFCCheck(self, srfc, tid):
		print "TID (TRFCCheck) is: #" + tid + "#"
		return False

	def TRFCCommit(self, srfc, tid):
		print "TID (TRFCCommit) is: #" + tid + "#"
		return

	def TRFCConfirm(self, srfc, tid):
		print "TID (TRFCConfirm) is: #" + tid + "#"
		return

	def TRFCRollback(self, srfc, tid):
		print "TID (TRFCRollback) is: #" + tid + "#"
		return

The class must have the 4 defined methods to handle the various stages of tRFC (Queued RFC). If the TRFCCheck method returns True, then the Registered RFC program is acknowledging that it has allready processed the transaction, so by default it should usually return False.
