Should fail with EBADF....
The fildes argument is not a valid open file descriptor, or the
argument cmd is F_SETLK or F_SETLKW, the type of lock, l_type,
is a shared lock (F_RDLCK), and fildes is not a valid file
descriptor open for reading, or the type of lock, l_type, is
an exclusive lock (F_WRLCK), and fildes is not a valid file
descriptor open for writing.
