=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>.
