orca::Pinger Interface Reference [Pinger] An interface which provides the well-known ping service. More... Inherited by pingserver::PingerI. List of all members. Public Member Functions double  ping (string hostname) throws PingException Detailed Description An interface which provides the well-known ping service. This is provided as an Ice interface because calling Unix 'ping' requires root priveliges, so it's hard to do from within a large C++ program (assuming you don't want to run the entire executable as super user). This interface allows a small component to be run with root priveliges, and provide this service to other non-superuser components. AlexB: Seems like a bit of a heavy-handed approach, but I'm not sure how else to do it... An obvious possibility is system("ping") and use some sed/grep magic to pull out the numbers and write to a file, then read the file. This might work but (a) it's brittle and a pain in the arse, and (b) it's hard to get meaningful errors if something goes wrong. Member Function Documentation double orca::Pinger::ping (  string  hostname  )  throws PingException   Returns: >=0 : a latency in milliseconds <0 : ping timed out. Warning: This function executes in the caller's thread. So it may wait for the ping to time out before returning. So, you should make sure that the Timeout value of the Ice call is larger than the timeout value of the server's ping call. The documentation for this interface was generated from the following file: pinger.ice
