示例1: Debounce

fpsTimeLast.update();
return true;
} else {
return false;
}
}示例2: receiveFrom
int ICMPSocketImpl::receiveFrom(void*, int, SocketAddress& address, int flags)
{
int maxPacketSize = _icmpPacket.maxPacketSize();
unsigned char* buffer = new unsigned char[maxPacketSize];
try
{

{
if (ts.isElapsed(_timeout))
{
// This guards against a possible DoS attack, where sending
// fake ping responses will cause an endless loop.
throw TimeoutException();
