I've been giving myself a crash course in C lately with the help
of a neighbor who lives a few floors down and have come across
the following lack of documentation: what in the heck is a 
message key?  Someone mentioned a function called ftok() earlier.
(about 20 msgs back)  I don't know what it is, but perusing some
talk code made it seem helpful.  Other than the fact that a
message key is a long integer I have no conception of what one
should look like.  What is a bad key versus a good key?
Info. about ftok() and message keys would be greatly appreciated.

				Thanks for the help,

PS If you know of a good reference for this stuff please let me
know.  You just can't cover all of Coherent and C in a 1000 page
book.
