TCPGetMyPort (socket) Returns port
Note: The flag is set according to whether Omnis was able to make a call to this external command.
This Web command is multi-threaded, allowing another thread to execute in the multi-threaded server while it runs. Note that the same socket cannot safely be used concurrently by more than one thread.
TCPGetMyPort is a command to return the number of the local TCP/IP port to which a given socket is bound.
Socket is an Omnis Long Integer field containing a connected socket, or a socket bound to a port.
Port is an Omnis Long Integer field which receives the port number, or an error code < 0. Possible error codes are listed in the Web Command Error Codes Appendix.
# Bind iPort to iSocket and use TCPGetMyPort to return the
# port to which iSocket is bound in lMyPort.
Calculate iPort as 6000
TCPSocket Returns iSocket
TCPBind (iSocket,iPort) Returns lStatus
TCPGetMyPort (iSocket) Returns lMyPort
TCPClose (iSocket) Returns lStatus
