TCPServiceGetPort

function

Library: TCP/IP client and server support (OMTCP legacy, OmniMark versions 4 - 6.0.1)
Include: omtcp.xin

Returns: the service port number the TCP service object listens to for an incoming connection

Declaration

define external integer function TCPServiceGetPort
      value TCPService this-TCPService
as "TCPServiceGetPort"

Purpose

This function is used to learn which service port number the TCP service object listens to for incoming connections. This API is particularly useful when you call TCPServiceOpen without stating a port number explicitly. In this case, TCPServiceOpen chooses an available port, and TCPServiceGetPort can then be used to learn about the chosen port.

Argument:

"this-TCPService" is an OMX component of type TCPService

Example

  local TCPService omdemo-service
  local integer port
  
  set omdemo-service to TCPServiceOpen
  set port to TCPServiceGetPort omdemo-service
  output "The selected service port for omdemo-service is %d(port)%n"
