Description

The function process-wait-local-with-timeout has same semantics as process-wait-with-timeout, but is "local", which here means that it does not interact with the scheduler. The scheduler does not call the wait function and hence never wakes the waiting process.

The timeout is in seconds.

The circumstances in which the function wait-function is called, and the restrictions on it, are as documented for process-wait-local except that the wait function can additionally be called when it times out.

process-wait-local-with-timeout returns t if a call to the wait function returns true. It returns nil if it times out.
