Guardian Procedure Calls Reference Manual

Condition Code Settings
These settings are obtained from the CLOSE procedure in the backup process; CHECKCLOSE
establishes these settings in the primary process:
indicates that an invalid file number was supplied or that the backup process does not exist.< (CCL)
indicates that the CLOSE was successful.= (CCE)
does not return from CHECKCLOSE.> (CCG)
Considerations
• Identification of the backup process
The system identifies the process to be affected by the CHECKCLOSE operation from the
process' mom field in the process control block (PCB). For named process pairs, this field is
automatically set up during the creation of a backup process.
• The condition code returned from CHECKCLOSE indicates the outcome of the CLOSE in the
backup process.
• See the CLOSE^FILE procedure Considerations (page 172).
