Sends messages to the MHP.
Before issuing the dc_clt_send_s function, the dc_rpc_open_s function with flags set to DCCLT_ONEWAY_SND or DCCLT_SNDRCV must be issued.

DCCLTER_INVALID_CLTID | -2544 | The client ID specified for cltid differs from the one received by the dc_clt_cltin_s function. |
DCCLTER_PORT_IN_USE | -2547 | Port numbers that can be assigned automatically by the operating system are insufficient. |
If the remote system releases the connection when the function sends a message to the remote system, depending on the length of the message, the function might not be able to detect that the connection has been released. However, a subsequent function might detect it. Keep this in mind when you create a CUP.
