.SH DESCRIPTION
+.IR "Note well" :
+This page documents interfaces provided in glibc up until version 2.1.
+Since version 2.2, glibc no longer provides these interfaces.
+Probably, you are looking for the APIs provided by the
+.I libdb
+library instead.
+
The routine
.BR dbopen (3)
is the library interface to database files.
