SSL_set_session(3) OpenSSL SSL_set_session(3) NNAAMMEE SSL_set_session - set a TLS/SSL session to be used during TLS/SSL con- nect SSYYNNOOPPSSIISS #include int SSL_set_session(SSL *ssl, SSL_SESSION *session); DDEESSCCRRIIPPTTIIOONN _S_S_L___s_e_t___s_e_s_s_i_o_n_(_) sets sseessssiioonn to be used when the TLS/SSL connection is to be established. _S_S_L___s_e_t___s_e_s_s_i_o_n_(_) is only useful for TLS/SSL clients. When the session is set, the reference count of sseessssiioonn is incremented by 1. If the session is not reused, the reference count is decremented again during _S_S_L___c_o_n_n_e_c_t_(_). Whether the session was reused can be queried with the _S_S_L___s_e_s_s_i_o_n___r_e_u_s_e_d(3) call. If there is already a session set inside ssssll (because it was set with _S_S_L___s_e_t___s_e_s_s_i_o_n_(_) before or because the same ssssll was already used for a connection), _S_S_L___S_E_S_S_I_O_N___f_r_e_e_(_) will be called for that session. NNOOTTEESS SSL_SESSION objects keep internal link information about the session cache list, when being inserted into one SSL_CTX object's session cache. One SSL_SESSION object, regardless of its reference count, must therefore only be used with one SSL_CTX object (and the SSL objects created from this SSL_CTX object).
