with-process-lock

$Revision: 5.0.2.4 $

Macro

Package: MULTIPROCESSING

Arguments: ((lock &key timeout norecursive seized whostate) &body body)

This macro executes the body with lock seized. Unlike mp:process-lock, mp:with-process-lock protects against a single process trying to seize a lock it already owns. If executed dynamically inside another mp:with-process-lock for the same lock, and if norecursive is nil, mp:with-process-lock is a no-op. If norecursive is t, an error is signaled. The default value of norecursive is nil.
