-  CIS 307: An example using Read/Write File Locks
-  [fcntl.h], [fcntl.c], [fcntlmain.c]
-
-In Stevens "Advanced Programming in the Unix Environment" we see ways to use
-the Unix service fcntl to lock portions of a file for reading and writing in
-the manner stated in the Reader and Writer problem [any number of readers at
-a time, but writers must operate alone]. Here we have three files that adapt
-and use the code from Stevens:
-
-*fcntl.h: Specification of the locking functions.
-*fcntl.c: Implementation of the locking functions.
-*fcntlmain.c: Driver that does a simple test of the locking functions.
-
-WARNING: A file lock request which is blocked can be interrupted by a
-signal. In this case the lock operation returns EINTR. Thus we may think we
-got a lock when we really don't. A solution is to block signals when
-locking. Another solution is to test the value returned by the lock
-operation and relock if the value is EINTR. Another solution, which we adopt
-here, is to do nothing about it.
