Prioritized locking

| Hi group,
I have several processes that are fighting to grab a semaphore to
access a region of shared memory. Of all of them I need to give special
priveleges to one of the process if it is also fighting to grab the
semaphore.
I know little about prioritized locks. Any links/references to them in
a multiprocess environment will be appreciated.
Thanks.

Theory and implementation are two different subjects.
For theory: consult a good book, like Jim Gray& Andreas Reuter's
"transaction processing".
For implementation: come back after reading the above book.
That will probably be a year from now ;-)
Let's synchronise our watches ...

Did you perform a search on your own with any key words?
Example:
