Member Function Documentation

virtual void net_instaweb::PthreadCondvar::Broadcast ( )

virtual

Broadcast to all threads waiting on condvar. mutex() must be held as with Signal().

Implements net_instaweb::ThreadSystem::Condvar.

virtual void net_instaweb::PthreadCondvar::Signal ( )

virtual

Signal the condvar, waking a waiting thread if any. mutex() must be held by caller. Example: { ScopedMutex lock(cv.mutex()); make_resource_available(); cv.Signal(); }

Implements net_instaweb::ThreadSystem::Condvar.

virtual void net_instaweb::PthreadCondvar::TimedWait ( int64  timeout_ms )

virtual

Wait for condition to be signaled, or timeout to occur. Works like Wait(), and cv.mutex() must be held on entry and re-taken on exit.

Implements net_instaweb::ThreadSystem::Condvar.

virtual void net_instaweb::PthreadCondvar::Wait ( )

virtual

Wait for condition to be signaled. mutex() must be held; it will be released and then reclaimed when a signal is received. Note that a Wait() may be terminated based on a condition being true, but the condition may no longer be true at the time the thread wakes up. Example: { ScopedMutex lock(cv.mutex()); while (status && !resource_available()) status = cv.wait(); if (status) { use_resource(); } }

Implements net_instaweb::ThreadSystem::Condvar.
