function

TCPServiceIsInError

Library: omtcp - TCP/IP client and server support Include: omtcp.xin

Return type: Boolean Returns:        True if the TCP service is in error; false otherwise.

Declaration

  define external switch function TCPServiceIsInError
        value TCPService this-TCPService
  as TCPServiceIsInError

Purpose

This function simply detects whether the TCP service is in error. This usually occurs when a TCPServiceOpen fails.

Errors in initiating a TCP service are recorded in the TCP service itself, or in the TCP connection object derived from it.

Argument:

• "this-TCPService" is an opaque object of type TCPService.

Example

  do when TCPServiceIsInError omdemo-service
     local stream errorReport variable

    TCPServiceGetStatusReport omdemo-service into errorReport
    output "TCPService Error:%n"
    repeat over errorReport
      output errorReport || "%n"
    again
  done
