NAME
    DBM_Filter::null - filter for DBM_Filter

SYNOPSIS
        use SDBM_File; # or DB_File, GDBM_File, NDBM_File, or ODBM_File
        use DBM_Filter ;

        $db = tie %hash, ...
        $db->Filter_Push('null');

DESCRIPTION
    This filter ensures that all data written to the DBM file is null terminated. This is useful
    when you have a perl script that needs to interoperate with a DBM file that a C program also
    uses. A fairly common issue is for the C application to include the terminating null in a string
    when it writes to the DBM file. This filter will ensure that all data written to the DBM file
    can be read by the C application.

    DBM_Filter, perldbmfilter
