process-interrupt

Arguments: process function &rest args

This function forces process to apply function to args when it next executes. When function returns, the original computation of process continues. If process is waiting when interrupted, it runs the interrupt function and then continues waiting. If process is not active, mp:process-interrupt makes it active for the interrupt function, then makes it inactive again. If additional interrupts are posted to a process when one is already posted, they are all run, but in undetermined order.

In order for process-interrupt to work as described, function must return normally. It cannot execute a non-local exit (via, for example, throw). If function does exit in a non-local manner, process will not continue its computation.

Processing an interrupt function can be interrupted by additional process interrupts that occur before the current one has finished executing.
