Thanks, Daniel. I'll update the docs to clarify this, if I get a moment.

As far as I can see from the documentation, t_check_trans() returns a boolean value and does not modify any data internally. Can anyone help me find out what the relevance of the t_check_trans() calls is? t_check_trans() is used to detect retransmissions. If a retransmission is received, then the last reply (if any) needs to be sent back, then t_check_trans() does an 'exit' internally.
