Everything I know about file locking, I've learned from the short
chapter on it in "Beginning Linux Programming" (WROX Press), part of a
chapter that I've only skimmed in "UNIX Systems Programming for
SYSVr4" (O'Reilly), and from the manual pages to `fcntl', `flock',
`lockf', `open', and `lockfile'. There is doubtless information in
the "POSIX Programmer's Guide" (O'Reilly), also, but I've not started
that one yet.
mis en place:
I know that there are several stand-alone programs for handling
file-locking, and that the `procmail' package has a fairly good setup
for that. INND apparently does as well; as does `mgetty-fax'.
`lockfile' --> procmail
`shlock' --> innd
`newslock' --> mgetty-fax
There is also: publib-0.26/liw/lockfile/*
** Publib looks like it might already be the library needing to be
created that was mentioned earlier... or at least a very good start.
`sysid' --> util-linux
libuuid.so --> libuuid
It would seem to me that things like this could be gleaned from the
sources to many programs, and put together into a shared library.
That will take a lot of work, for certain. What's in Midnight
Q: Who will do the work? I am doubtful of my own ability to be of
much help... I'd like to see what gets done by the programmer though.
Did I miss anything? I'm reading INND manuals today... I want to
learn how to set up a news box, so I'm going to fill a partition with
a spool. (I wonder if I'll have it working by dark?)
 I'm a beginner C programmer... strike that. Not programmer, but
code reader, or person who attempts to understand code. ;-)
 It's someplace within a heap of books... the heap without
bookmarks stuck inside any of the first few chapters, yet.
