Struct FcntlLockTable

Source

pub struct FcntlLockTable { /* private fields */ }

Expand description

All record locks for a Host.

Implementations§

Source §

impl FcntlLockTable

Source

pub fn new() -> Self

Source

pub fn set_lock( &mut self, file_id: FileId, requested_range: Range<usize>, requested_owner: &LockOwner, requested_access: FlockType, ) -> Result<(), LockError>

Source

pub fn get_coalesced_conflicting_lock( &self, file_id: FileId, requested_range: Range<usize>, requested_owner: &LockOwner, requested_access: FlockType, ) -> Option<(LockOwner, Range<usize>, FlockType)>

Return one of the locks that would conflict with the requested lock, if any. Intended for fcntl operations like F_GETLK.

Source

pub fn remove_owner(&mut self, file_id: FileId, requested_owner: &LockOwner)

Drop all of the given owner’s locks on the given file.
