/* ** RCCondition - C++ wrapper around NSPR's PRCondVar ** ** Conditions have a notion of timeouts. A thread that waits on a condition ** will resume execution when the condition is notified OR when a specified ** interval of time has expired. ** ** Most applications don't adjust the timeouts on conditions. The literature ** would argue that all threads waiting on a single condition must have the ** same semantics. But if an application wishes to modify the timeout with ** (perhaps) each wait call, that modification should be done consistantly ** and under protection of the condition's associated lock. ** ** The default timeout is infinity.
