start-customs

Arguments: &optional name

This function ignores its argument and simply calls start-scheduler if necessary. Calls to start-customs are deprecated and should be replaced with calls to start-scheduler.

In earlier releases, if non-lisp threads were going to use callback functions to invoke lisp code, then a "customs" process had to be running to assign each such thread a lisp process, when the thread first tries to invoke lisp code. start-customs started such a process. However, in Allegro CL 7.0, this is all handled automatically and tranparently to the programmer. Thus this function is no longer needed. It is kept (and calls start-scheduler) because there may be applications that call start-customs to start multiprocessing as well as to perform the (no longer necessary) task of handling the call backs described above.

See multiprocessing.htm for general information on multiprocessing in Allegro CL.
