Guardian Procedure Calls Reference Manual

Considerations
• A successful status indication from SENDBREAKMESSAGE does not imply that the process
has received the message, only that it has been sent.
• If the process-id designates a member of a named process pair, the break-on-device
message delivery will automatically be retried to the backup process if a failure or path switch
occurs.
• A break-on-device system message is delivered to the $RECEIVE file of the target process. For
the format of the interprocess system messages, see the Guardian Procedure Errors and
Messages Manual.
• SENDBREAKMESSAGE cannot be used for a high-PIN unnamed process because a high PIN
cannot fit into process-id; BREAKMESSAGE_SEND_ must be used instead. However, it
can use SENDBREAKMESSAGE for a high-PIN named process.
