For details on the format, see the explanation in the applicable OpenTP1 Protocol manual.

The function dc_mcf_resend() resends an already sent logical message to other system. The resent message is treated as a new message separate from the already sent message. The message to be resent can be selected using information about already sent messages as follows:

• Output-destination logical terminal name
• Message sequence number
• Message type (general branch or priority branch)

Before a node can use the function dc_mcf_resend(), it must use a queue (disk queue) for holding already sent messages.

If the message to be resent was not sent, the function dc_mcf_resend() returns with an error. It also returns with an error if the message to be resent is not found in the output queue.

The values to be specified for the arguments and the return values vary with the communication protocol in use. For details, see the explanation in the applicable OpenTP1 Protocol manual.

The message resend order varies depending on the mcfmuap -c order specification in the UAP common definition of the MCF manager definition.
