DBM_Filter::null(3perl)          Perl Programmers Reference Guide         DBM_Filter::null(3perl)



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.
