#8661 closed bug (fixed)

fcntl(fd, F_GETLK, ...) violates POSIX

Reported by: pdziepak Owned by: pdziepak
Priority: normal Milestone: R1
Component: System/POSIX Version: R1/Development
Keywords: Cc:
Blocked By: Blocking:
Platform: All


The standard states that F_GETLK should check whether given lock would be blocked by another one and return description of the conflicting one (or set l_type to F_UNLCK if there is no collision).

Current implementation of F_GETLK performs completely different actions, it "Retrieves the first lock that has been set by the current team". Moreover, if there are no locks (advisory_locking == NULL) an error is returned instead of l_type set to F_UNLCK.
