26 DBM_Filter::null - filter for DBM_Filter
30 use SDBM_File; # or DB_File, or GDBM_File, or NDBM_File, or ODBM_File
34 $db->Filter_Push('null');
38 This filter ensures that all data written to the DBM file is null
39 terminated. This is useful when you have a perl script that needs
40 to interoperate with a DBM file that a C program also uses. A fairly
41 common issue is for the C application to include the terminating null
42 in a string when it writes to the DBM file. This filter will ensure that
43 all data written to the DBM file can be read by the C application.
