144 SSL_CTX_add_session, SSL_add_session, SSL_CTX_remove_session, SSL_remove_session \- manipulate session cache
146 .IX Header "SYNOPSIS"
148 \& #include <openssl/ssl.h>
151 \& int SSL_CTX_add_session(SSL_CTX *ctx, SSL_SESSION *c);
152 \& int SSL_add_session(SSL_CTX *ctx, SSL_SESSION *c);
155 \& int SSL_CTX_remove_session(SSL_CTX *ctx, SSL_SESSION *c);
156 \& int SSL_remove_session(SSL_CTX *ctx, SSL_SESSION *c);
159 .IX Header "DESCRIPTION"
160 \&\fISSL_CTX_add_session()\fR adds the session \fBc\fR to the context \fBctx\fR. The
161 reference count for session \fBc\fR is incremented by 1. If a session with
162 the same session id already exists, the old session is removed by calling
165 \&\fISSL_CTX_remove_session()\fR removes the session \fBc\fR from the context \fBctx\fR.
166 SSL_SESSION_free(3) is called once for \fBc\fR.
168 \&\fISSL_add_session()\fR and \fISSL_remove_session()\fR are synonyms for their
169 SSL_CTX_*() counterparts.
172 When adding a new session to the internal session cache, it is examined
173 whether a session with the same session id already exists. In this case
174 it is assumed that both sessions are identical. If the same session is
175 stored in a different \s-1SSL_SESSION\s0 object, The old session is
176 removed and replaced by the new session. If the session is actually
177 identical (the \s-1SSL_SESSION\s0 object is identical), \fISSL_CTX_add_session()\fR
178 is a no-op, and the return value is 0.
180 .IX Header "RETURN VALUES"
181 The following values are returned by all functions:
184 \& The operation failed. In case of the add operation, it was tried to add
185 \& the same (identical) session twice. In case of the remove operation, the
186 \& session was not found in the cache.
191 \& The operation succeeded.
