    Usage void lockDB ( $database )
    Purpose To place a file lock on disk to prevent further writing to the database
    Availability txtSQL >= 2.2.0 Beta

    This function will return TRUE if $database was successfully locked and FALSE otherwise. A file lock is basically a file created that tells txtSQL that it is locked.

    Example 12: locked() Copy to Clipboard
    <?php
    if ( $sql->lockdb('testDB') )
    {
        print
    'testDB is locked';
    }
    else
    {
        print
    'testDB could not be locked, txtSQL said: '.$sql->get_last_error();
    }
    ?>
