>Description:
If file is locked with flock() function and when I try to use fcntl(F_GETLK) function then it returns flock structure with following fileds:

l_type != F_UNLCK
l_pid == -1

if l_type isn't equal to F_UNLCK then I suppose that file is locked, but l_pid is always equal to -1.

From the fcnlt(2) manual page:

Note that flock(2) and fcntl(2) locks may be safely used concurrently.

That's why I think that it is a bug in flock() or fcntl() implementation.
