DBM_Filter::null(3) Perl Programmers Reference Guide DBM_Filter::null(3)NAMEDBM_Filter::null - filter for DBM_Filter
use SDBM_File; # or DB_File, or GDBM_File, or NDBM_File, or ODBM_File
use DBM_Filter ;
$db = tie %hash, ...
This filter ensures that all data written to the DBM file is null ter‐
minated. 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 com‐
mon 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.
