DBM_Filter::null - filter for DBM_Filter

use SDBM_File; # or DB_File, GDBM_File, NDBM_File, or ODBM_File use DBM_Filter ; $db = tie %hash, … $db->Filter_Push(null);

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.
