Declaration

  define external function TCPConnectionPut
         value TCPConnection this-TCPConnection
        from value stream characters-to-be-put
      timeout value integer timeout-in-milliseconds optional
  as TCPConnectionPut

This function writes characters to a TCP connection, sending them to the receiver.

TCPConnectionPut can be formulated in terms of TCPConnectionGetOutput as follows:

  define function TCPConnectionPut
         value TCPConnection this-TCPConnection
      from value stream characters-to-be-put
     timeout value integer timeout-in-milliseconds optional
  as
     do when timeout-in-milliseconds is specified
        set TCPConnectionGetOutput this-TCPConnection
          timeout timeout-in-milliseconds
        to characters-to-be-put
     else
        set TCPConnectionGetOutput this-TCPConnection
           to characters-to-be-put
     done

The difficulties inherent with multiple derived outputs apply to uses of TCPConnectionPut also. That is, only one external output from a connection can be derived (active) at any one time. The current external output must be closed before you can issue a TCPConnectionPut.

Note that sequential uses of TCPConnectionPut in the absence of any use of TCPConnectionGetOutput is allowed.

Any attempt to do a TCPConnectionPut when there is already active output derived from TCPConnectionGetOutput output is not allowed and will result in an OmniMark external function exception.

Any attempt to do a TCPConnectionPut when the associated TCP connection has been closed using TCPConnectionClose is in error, in the same manner as for an external output derived from the TCP connection.

Arguments:

• "this-TCPConnection" is an OMX component of type TCPConnection.
• "characters-to-be-put" are the characters that will be put in the output stream.
• "timeout-in-milliseconds" is the length of time the function will run before terminating.

Example:

  local TCPConnection TCP-Conn

  set TCP-Conn to TCPConnectionOpen on "localhost" at 5300

  TCPConnectionPut TCP-Conn from "hello world"
  TCPConnectionPut TCP-Conn from ((("*" ||* 78) || "%n") ||* 40)
