Library: TCP/IP client and server support (OMTCP) legacy Include: omtcp.xin

Return type: Integer Returns:

Declaration

define external integer function tcp-port
      value tcp-service Service

Argument definitions

Service

is an existing tcp-service object.

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

Requirements

You must include the following line at the beginning of your OmniMark program:

  include "omtcp.xin"

Service must represent an existing service (else external exception TCP05).

Usage Notes

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

Example

  
  local tcp-service Demo
  local integer Port
  
  set Demo to tcp-create-service
  set Port to tcp-port Demo
  output "The selected service port for Demo is %d(Port)%n"
