DBM_Filter::null

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

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

DESCRIPTION
14       This filter ensures that all data written to the DBM file is null ter‐
15       minated. This is useful when you have a perl script that needs to
16       interoperate with a DBM file that a C program also uses. A fairly com‐
17       mon issue is for the C application to include the terminating null in a
18       string when it writes to the DBM file. This filter will ensure that all
19       data written to the DBM file can be read by the C application.
