23.7 Alphabetized Database-Map Types

Recall that the K configuration command (Section 23.2) is used like this:

Kname type args

The type determines the type of database map that will be used. For example, the type btree causes a db(3)-format database file to be used, whereas the type dequote causes an internal routine of sendmail's to be called.

In this section we present all the types in alphabetical order. They are summarized in Table 23-2 of Section 23.2.2. Most interaction with these types can be watched by using the -d38.2 debugging switch (-d38.2). Some specialty database maps use other debugging switches, which we indicate where appropriate.
