DBM_Filter::null - phpMan

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.
