## gate-open-p

Arguments: gate

The gate argument must have been allocated with make-gate. Returns true if gate's state is open and returns `nil` if it is closed.

As described in the documentation for gates linked to below, gate-open-p is handled specially by process-wait, and so code which uses gates runs more efficiently. The speedup can be significant if the process often waits.

See Gates in multiprocessing.htm for more information. See also make-gate, open-gate, and close-gate.
