Sorry, I disagree here...GETLK is really a misnomer, IMO. TESTLK would have been a better name.
GETLK are used is to "get the first lock".
It's a way to test whether a particular lock can be applied, and to return information about a conflicting lock if it can't. If, for instance there is no conflicting lock, then you don't "get" any lock information back (l_type just gets reset to F_UNLCK).
While I kinda see your point, it isn't what GETLK does; it really does get you information about the first lock -- you're not testing anything. It is also the terminology used in the POSIX standard.
