This module provides functionality for managing pairs of input and output ports. We have plans to allow a number of different strategies for doing this.
(struct connection (timer i-port o-port custodian close?) #:extra-constructor-name make-connection) timer : timer? i-port : input-port? o-port : output-port? custodian : custodian? close? : boolean?
A connection is a pair of ports (i-port and o-port) that is ready to close after the current job if close? is #t. Resources associated with the connection should be allocated under custodian. The connection will last until timer triggers.
(start-connection-manager) → connection-manager?
Runs the connection manager (now just the timer manager).
(new-connection cm timeout i-port o-port cust close?) → connection? cm : connection-manager? timeout : number? i-port : input-port? o-port : output-port? cust : custodian? close? : boolean?
Constructs a connection with a timer with a trigger of timeout that calls kill-connection!.
Closes the ports associated with c, kills the timer, and shuts down the custodian.
