Import : omtcp.xmd

Returns:

Declaration

define external integer function tcp.port
   of value tcp.service Service

Argument definitions

Service: is an existing tcp.service object.

Purpose

Use tcp.port to learn which port number the TCP service object listens on for incoming connections.

Usage Notes

This API is particularly useful when you call tcp.create-service without specifying a port.

Example

  import "omtcp.xmd" prefixed by tcp.
  
  process
     local tcp.service Demo
     local integer Port
  
     set Demo to tcp.create-service
     set Port to tcp.port of Demo
     output "The selected service port for Demo is %d(Port)%n"
