DBM_Filter::null(Perl Programmers Reference GDBM_Filter::null(3p)


NAME
       DBM_Filter::null - filter for DBM_Filter

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');

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.
