SSL_CTX_sessions(3ssl)

SSL_CTX_sessions3ssl

Access internal session cache

Usage

 #include <openssl/ssl.h>
 LHASH_OF(SSL_SESSION) *SSL_CTX_sessions(SSL_CTX *ctx);

Overview

SSL_CTX_sessions() returns a pointer to the lhash databases containing the internal session cache for ctx.

Notes

The sessions in the internal session cache are kept in an 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 LHASH(3) operations, so that the database must not be modified directly but by using the SSL_CTX_add_session(3) family of functions.

Return values

SSL_CTX_sessions() returns a pointer to the lhash of SSL_SESSION.
