Guardian Procedure Calls Reference Manual

Returned Value
INT
A file-system error code that indicates the outcome of the call. A successful indication implies only
that the message has been sent, not that it has been received.
Considerations
If processhandle designates a member of a named process pair, and if a failure or a path
switch occurs, delivery of the break-on-device message is automatically retried to the backup
process. For detailed information about system messages, see the Guardian Procedure Errors and
Messages Manual.
Example
error := BREAKMESSAGE_SEND_( proc-handle, file-number, tag );

Programmer's Guide.
