NAME

       cfdpclock - CFDP daemon task for managing scheduled events

SYNOPSIS

       cfdpclock

DESCRIPTION

       cfdpclock is a background "daemon" task that periodically performs scheduled CFDP activities.  It is
       spawned automatically by cfdpadmin in response to the 's' command that starts operation of the CFDP
       protocol, and it is terminated by cfdpadmin in response to an 'x' (STOP) command.

       Once per second, cfdpclock takes the following action:

           First it scans all inbound file delivery units (FDUs).  For each one whose check timeout deadline has
           passed, it increments the check timeout count and resets the check timeout deadline.  For each one
           whose check timeout count exceeds the limit configured for this node, it invokes the Check Limit
           Reached fault handling procedure.

           Then it scans all outbound FDUs.  For each one that has been Canceled, it cancels all extant PDU
           bundles and sets transmission progress to the size of the file, simulating the completion of
           transmission.  It destroys each outbound FDU whose transmission is completed.

EXIT STATUS

       "0" cfdpclock terminated, for reasons noted in the ion.log file.  If this termination was not commanded,
           investigate and solve the problem identified in the log file and use cfdpadmin to restart cfdpclock.

       "1" cfdpclock was unable to attach to CFDP protocol operations, probably because cfdpadmin has not yet
           been run.

FILES

       No configuration files are needed.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

       The following diagnostics may be issued to the ion.log log file:

       cfdpclock can't initialize CFDP.
           cfdpadmin has not yet initialized CFDP protocol operations.

       Can't dispatch events.
           An unrecoverable database error was encountered.  cfdpclock terminates.

       Can't manage links.
           An unrecoverable database error was encountered.  cfdpclock terminates.
