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



DBM_Filter::null
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.
