APPENDIX B. THE CLIM-SYS PACKAGE


B.2 Multi-processing

Most Lisp implementations provide some form of multi-processing. CLIM provides a set of
functions that implement a uniform interface to the multi-processing functionality.

=> make-process function &key name [Function]
Creates a process named name. The new process will evaluate the function function. On systems
that do not support multi-processing, make-process will signal an error.

=> destroy-process process [Function]
Terminates the process process. process is an object returned by make-process.

=> current-process [Function]
Returns the currently running process, which will be the same kind of object as would be returned
by make-process.

=> all-processes [Function]
Returns a sequence of all of the processes.

=> process-wait reason predicate [Function]
Causes the current process to wait until predicate returns true. reason is a "reason" for waiting,
usually a string. On systems that do not support multi-processing, process-wait will loop until
predicate returns true.

=> process-wait-with-timeout reason timeout predicate [Function]
Causes the current process to wait until either predicate returns true, or the number of seconds
specified by timeout has elapsed. reason is a "reason" for waiting, usually a string. On systems
that do not support multi-processing, process-wait-with-timeout will loop until predicate
returns true or the timeout has elapsed.

=> process-yield [Function]
Allows other processes to run. On systems that do not support multi-processing, this does
nothing.

=> process-interrupt process function [Function]
Interrupts the process process and causes it to evaluate the function function. On systems that
do not support multi-processing, this is equivalent to funcall'ing function.

=> without-scheduling &body body [Macro]
Evaluates body in a context that is guaranteed to be free from interruption by other processes.
On systems that do not support multi-processing, without-scheduling is equivalent to progn.
