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.
