+.LP
+The \fBsize_t\fP type shall be defined as described in \fI<stddef.h>\fP
+\&.
+.LP
+The \fI<ndbm.h>\fP header shall define the \fBDBM\fP type.
+.LP
+The following constants shall be defined as possible values for the
+\fIstore_mode\fP argument to \fIdbm_store\fP():
+.TP 7
+DBM_INSERT
+Insertion of new entries only.
+.TP 7
