Package: mp

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

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

See also process-unlock, process-lock-locker, and make-process-lock.
