$db->Filter_Push('null');
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.
