[Openmcl-devel] new function ccl:wait-for-signal

[R. Matthew Emerson]

For those of you who don't avidly read the commit logs, I thought I would mention a new function ccl:wait-for-signal that was added to the trunk a few weeks ago.


ccl:wait-for-signal s duration

Wait until signal number s is received or until duration seconds have passed by.

If s is a signal number that is outside the range of valid signals, or is reserved by the lisp for its own use, an error is signaled.  (Currently, an error will always be signaled on Windows.)


There are some obvious enhancements that could be made (e.g., provide a way for a program to know which signals are reserved for use by the lisp itself), but it might be useful as is.
