process-reset
interrupts the execution of process and "throws away" its current state. Upon resuming execution, the process calls its function with its initial argument and priority.
process-reset
modifies the dynamic execution state of process. It performs a non-local exit from the currently running function, to cause the process's main function to return. unwind-protect
forms will be run.
process-reset
does not modify any of the attributes of the process, in particular its priority, items on the plist, or accumulated run-time.
Since process-reset
causes an asynchronous non-local exit, it is possible that it can occur within an unwind-protect
cleanup form or before data used by an unwind-protect
cleanup form has been initialized. In some cases, not all cleanups within that form will be run.
