BREAKMESSAGE_SEND_ Procedure
specifies the file number by which the receiving process identifies the open of the
process that is sending the break-on-device message.
breaktag input
INT .EXT:ref:2
if present, specifies a user-defined value to be delivered in the break-on-device
message. This value corresponds to the break tag value that can be supplied to
an access method with SETPARAM function 3.
If this parameter is omitted, 0 is used.
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. Refer to the
Guardian Procedure Errors and Messages Manual
for detailed information about system messages.
Example
error := BREAKMESSAGE_SEND_( proc-handle, file-number, tag );
