-
- =head1 SYNOPSIS
-
- use SDBM_File; # or DB_File, or GDBM_File, or NDBM_File, or ODBM_File
- use DBM_Filter ;
-
- $db = tie %hash, ...
- $db->Filter_Push('null');
-
- =head1 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.
