In the next release of ifhp you can do:
sync=|/path_to_program [options]
pagecount=|/path_to_program [options]
waitend=|/path_to_program [options]
This will cause IFHP to start the program with:
STDIN - </dev/null
STDOUT - reporting 'status' information
STDERR - logging/error status information
Information written to STDOUT should have the format: key=value
KEY VALUE
sync 1 - for sync operation, indicates sync is done
(note: can also send 'pagecount=nnn', as some sync stuff can
also get pagecount at same time, so you can optimize this).
waitend 1 - for waitend operation, indicates waitend is done
(note: can also send 'pagecount=nnn', as some waitend stuff can
also get pagecount at same time, so you can optimize this).
pagecount nnn - pagecounter value
(note: if pagecount is returned by sync or waitend you do not call
the pagecount stuff.)
OR: the sync and waitend can exit with status 0 indicating
success (without writing anything to STDOUT)
a non-zero exit value causes ifhp to exit with the
same status; coredump, etc., cause exit with JABORT
(you get the idea).
NOTE: if pagecount exits with no pagecount information
or the sync writes 'pagecount=0' to STDOUT
then this indicates that no pagecounter value is available.
