%description
This package provides access to platform dependent file locking APIs:

*
<https://www.gnu.org/software/libc/manual/html_node/Open-File-Description-Locks.html
Open file descriptor locking> on Linux ("Lukko.OFD") * BSD-style 'flock(2)'
locks on UNIX platforms ("Lukko.FLock") * Windows locking via
<https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-lockfilee
LockFileEx> ("Lukko.Windows") * No-op locking, which throws exceptions
("Lukko.NoOp") * "Lukko" module exports the best option for the target platform
with uniform API.

There are alternative file locking packages:

* "GHC.IO.Handle.Lock" in 'base >= 4.10' is good enough for most use cases.
However, uses only 'Handle's so these locks cannot be used for intra-process
locking. (You should use e.g. 'MVar' in addition).

* <https://hackage.haskell.org/package/filelock filelock> doesn't support OFD
locking.

/Lukko/ means lock in Finnish.

Submodules "Lukko.OFD", "Lukko.Windows" etc are available based on following
conditions.

' if os(windows) cpp-options: -DHAS_WINDOWS_LOCK

elif (os(linux) && flag(ofd-locking)) cpp-options: -DHAS_OFD_LOCKING
cpp-options: -DHAS_FLOCK

elif !(os(solaris) || os(aix)) cpp-options: -DHAS_FLOCK '

"Lukko.FLock" is available on not (Windows or Solaris or AIX).
"Lukko.NoOp" is always available.
