Mail::Box::Locker::POSIX - lock a folder using kernel file-locking
INHERITANCE
Mail::Box::Locker::POSIX

DESCRIPTION
This locker object is created by the folder to get an exclusive lock on the file which contains the data using the kernel's POSIX
facilities. This lock is created on a separate file-handle to the folder file, so not the handle which is reading. Not all platforms
support POSIX locking.

DIAGNOSTICS
Warning: Folder $folder already lockf'd
Error: Package $package does not implement $method.
Fatal error: the specific package (or one of its superclasses) does not implement this method where it should. This message means that
some other related classes do implement this method however the class at hand does not. Probably you should investigate this and
probably inform the author of the package.
Error: Unable to check lock file $filename for $folder: $!
To check whether the filename is used to flock a folder, the file must be opened. Apparently this fails, which does not mean that the
folder is locked neither that it is unlocked.
Error: Unable to open POSIX lock file $filename for $folder: $!
For POSIX style locking, a folder it must be opened, which does not succeed for the specified reason.
Error: Will never get a POSIX lock at $filename for $folder: $!
Tried to lock the folder, but it did not succeed. The error code received from the OS indicates that it will not succeed ever, so we
do not need to try again.
