monitor-processes-predicate

Syntax:

monitor-processes-predicate

You can use the Common Lisp macro setf with this function to specify a different function for determining whether monitoring occurs in a process:

(setf (monitored-processes-predicate) function) 

The function that you specify should take one argument, a process, and should return one value. A process is monitored if the result returned by the following form has a non-nil value:

(funcall (monitored-processes-predicate) process) 

If you have modified the value of monitored-processes-predicate, you can restore the default behavior with the following form:

(setf (monitored-processes-predicate) nil) 

See the chapter "The Multitasking Facility" in the Advanced User's Guide for more information about processes.
