Return type: Switch Returns:

Declaration

define external switch function tcp.wait-for-input
  from    value	tcp.connection	Connection
  timeout value	integer		ms            optional

Argument definitions

Connection

is an existing tcp connection.

ms

is how long the function will wait for at least one character, expressed in milliseconds.

Use tcp.wait-for-input to test if there are characters available from a source on the TCP connection object.

Requirements

Connection must exist (else external exception TCP05).

Example

  
  import "omtcp.xmd" prefixed by tcp.
  process
     local tcp.connection Connection-1
  
     set Connection-1 to tcp.connect to "localhost" on 5300
  
     repeat
        exit unless tcp.wait-for-input from Connection-1 timeout 2000
        output tcp.get-string from Connection-1
     again
