\&\fISSL_CTX_sessions()\fR returns a pointer to the lhash databases containing the
internal session cache for \fBctx\fR.
.SH "NOTES"
.IX Header "NOTES"
The sessions in the internal session cache are kept in an
\&\s-1\fILHASH\s0\fR\|(3) type database. It is possible to directly
access this database e.g. for searching. In parallel, the sessions
form a linked list which is maintained separately from the
\&\s-1\fILHASH\s0\fR\|(3) operations, so that the database must not be
modified directly but by using the
\&\fISSL_CTX_add_session\fR\|(3) family of functions.
