GetUdpPort
Script function world.GetUdpPort Read about scripting Type Method Summary Find a free port for UDP listening Prototype `long GetUdpPort(long First, long Last);` View list of data type meanings Description `This function finds a free port for use by MUSHclient as a UDP listener. It operates by scanning all open worlds for ports in use by UdpListen. It then works through the range you specify to find one that is not in use. However this test is only for port used by MUSHclient. There is no guarantee that the port is not in use by another application. The intention is for plugin writers to use it to find a port in a range (say, 4000 to 4100) which is not in use by another plugin, or the same plugin in another world. The First and Last arguments are port numbers, inclusive, that you wish to be scanned. eg. GetUdpPort (4000, 4100) would find a port in the range 4000 to 4100 inclusive. The port numbers must be greater than zero and less than 65535. Also the last port number must be greater than or equal to the first port number.` VBscript example
