NAME
       Apache::Session::Lock::Sybase - Provides mutual exclusion using Sybase

SYNOPSIS
        use Apache::Session::Lock::Sybase;

        my $locker = Apache::Session::Lock::Sybase->new;

        $locker->acquire_read_lock($ref);
        $locker->acquire_write_lock($ref);
        $locker->release_read_lock($ref);
        $locker->release_write_lock($ref);
        $locker->release_all_locks($ref);

DESCRIPTION
       Apache::Session::Lock::Sybase fulfills the locking interface of Apache::Session.  Mutual
       exclusion is achieved through the use of Sybase's sp_getapplock and sp_releaseapplock
       functions. Sybase does not support the notion of read and write locks, so this module only
       supports exclusive locks.  When you request a shared read lock, it is instead promoted to
       an exclusive write lock.

CONFIGURATION
       The module must know how to connect to your MySQL database to acquire locks.  You must
       provide a datasource name, a user name, and a password.  These options are passed in the
       usual Apache::Session style, and are very similar to the options for
       Apache::Session::Store::Sybase.  Example:

        tie %hash, 'Apache::Session::Sybase', $id, {
            LockDataSource => 'dbi:sybase:database',
            LockUserName   => 'database_user',
            LockPassword   => 'K00l'
        };

       Instead, you may pass in an already opened DBI handle to your database.

        tie %hash, 'Apache::Session::Sybase', $id, {
            LockHandle => $dbh
        };
