TCPConnectionGetPeerName

function

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

Returns: an official peer hostname or an IP address if no name is available

Declaration

define external stream function TCPConnectionGetPeerName
      value TCPConnection this-TCPConnection
as "TCPConnectionGetPeerName"

Purpose

This function is used to get the official name of the peer host on the other side of the connection. If TCPConnectionGetPeerName fails to get the official name, it returns its IP address. The IP address is returned in a dotted decimal format (for example, "123.123.123.45").

If the passed TCPConnection object is closed or was never connected, then this function returns a distinct value that doesn't look like a valid peer name and causes the TCPConnection object to be in error. If no peer name is available, but the connection is legitimate, this function returns the peer's IP address.

Argument:

"this-TCPConnection" is an OMX component of type TCPConnection.

Example:

  local TCPService omdemo-service
  local TCPConnection client
  
  set omdemo-service to TCPServiceOpen at 5600
  
  repeat
     set client to TCPServiceAcceptConnection omdemo-service
     output "Request from " || "g"% TCPConnectionGetPeerName client || "%n"
     ;process request
  again
