Box::Locker::Multi(3)

NAME
Mail::Box::Locker::Multi - lock a folder in all ways which work

CLASS HIERARCHY
 Mail::Box::Locker::Multi
 is a Mail::Box::Locker
 is a Mail::Reporter

SYNOPSIS
 See Mail::Box::Locker

DESCRIPTION
The "::Multi" locker locks a folder in each way it can. This way, the chance is highest that any other program will leave the folder alone during our access to it.

NFS-lock and Flock are tried. More may be added when the ways to lock are extended. DotLock overlaps with NFS-lock, but NFS-lock is safer, so that version is prefered.

        Array of locker types and locker objects to be used to lock one folder. The type names are converted into objects.

        Some locking types are not available on some platforms, so they will not be excluded from the default list (NFS POSIX Flock).
