cml.ss: Concurrent ML Compatibility

To load: (require (lib "cml.ss"))

This library defines a number of procedures that wrap MzScheme concurrency procedures. The wrapper procedures have names and interfaces that more closely match those of Concurrent ML.

(spawn thunk)      PROCEDURE

Equivalent to (thread/suspend-to-kill thunk) (see section 7.1 in PLT MzScheme: Language Manual).

(channel)      

procedure

Equivalent to (make-channel) (see section 7.5 in PLT MzScheme: Language Manual).

(channel-recv-evt channel)      PROCEDURE

Equivalent to channel.

(channel-send-evt channel v)      PROCEDURE

Equivalent to (channel-put-evt channel v) (see section 7.5 in PLT MzScheme: Language Manual).

(thread-done-evt thread)      PROCEDURE

Equivalent to (thread-dead-waitable thread) (see section 7.2 in PLT MzScheme: Language Manual).

(current-time)      PROCEDURE

Equivalent to (current-inexact-milliseconds) (see section 15.1 in PLT MzScheme: Language Manual).

(time-evt x)      PROCEDURE

Equivalent to (alarm-evt x) (see section 7.6 in PLT MzScheme: Language Manual).
