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.
