#include <openssl/ssl.h> long SSL_CTX_sess_set_cache_size(SSL_CTX *ctx, long t); long SSL_CTX_sess_get_cache_size(SSL_CTX *ctx);
SSL_CTX_sess_get_cache_size() returns the currently valid session cache size.
If adding the session makes the cache exceed its size, then unused sessions are dropped from the end of the cache. Cache space may also be reclaimed by calling SSL_CTX_flush_sessions(3) to remove expired sessions.
If the size of the session cache is reduced and more sessions are already in the session cache, old session will be removed at the next time a session shall be added. This removal is not synchronized with the expiration of sessions.
SSL_CTX_sess_get_cache_size() returns the currently valid size.
