=head1 NAME
SSL_CTX_sessions - access internal session cache
=head1 SYNOPSIS
#include <openssl/ssl.h>
struct lhash_st *SSL_CTX_sessions(SSL_CTX *ctx);
=head1 DESCRIPTION
SSL_CTX_sessions() returns a pointer to the lhash databases containing the
internal session cache for B<ctx>.
=head1 NOTES
The sessions in the internal session cache are kept in an
L<LHASH(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
L<LHASH(3)> operations, so that the database must not be
modified directly but by using the
L<SSL_CTX_add_session(3)> family of functions.
=head1 RETURN VALUES
SSL_CTX_sessions() returns a pointer to the lhash of B<SSL_SESSION>.
