16 This filter ensures that all data written to the DBM file is null
17 terminated. This is useful when you have a perl script that needs to
18 interoperate with a DBM file that a C program also uses. A fairly
19 common issue is for the C application to include the terminating null
20 in a string when it writes to the DBM file. This filter will ensure
21 that all data written to the DBM file can be read by the C application.
