Variants§

§

EACCES

Operation is prohibited by locks held by other processes.

§

EAGAIN

Operation is prohibited by locks held by other processes.

§

EBADF

fd is not an open file descriptor, or the command was F_SETLK or F_SETLKW and the file descriptor open mode doesn’t match with the type of lock requested.

§

EDEADLK

It was detected that the specified F_SETLKW command would cause a deadlock.

§

EFAULT

lock is outside your accessible address space.

§

EINTR

For F_SETLKW, the command was interrupted by a signal. For F_GETLK and F_SETLK, the command was interrupted by a signal before the lock was checked or acquired. Most likely when locking a remote file (e.g. locking over NFS), but can sometimes happen locally.

§

EINVAL

For F_DUPFD, arg is negative or is greater than the maximum allowable value. For F_SETSIG, arg is not an allowable signal number.

§

EMFILE

For F_DUPFD, the process already has the maximum number of file descriptors open.

§

ENOLCK

Too many segment locks open, lock table is full, or a remote locking protocol failed (e.g. locking over NFS).

§

EPERM

Attempted to clear the O_APPEND flag on a file that has the append-only attribute set.
