131 .IX Title "SSL_CTX_free 3"
132 .TH SSL_CTX_free 3 "2007-03-28" "0.9.8e" "OpenSSL"
134 SSL_CTX_free \- free an allocated SSL_CTX object
136 .IX Header "SYNOPSIS"
138 \& #include <openssl/ssl.h>
142 \& void SSL_CTX_free(SSL_CTX *ctx);
145 .IX Header "DESCRIPTION"
146 \&\fISSL_CTX_free()\fR decrements the reference count of \fBctx\fR, and removes the
147 \&\s-1SSL_CTX\s0 object pointed to by \fBctx\fR and frees up the allocated memory if the
148 the reference count has reached 0.
150 It also calls the \fIfree()\fRing procedures for indirectly affected items, if
151 applicable: the session cache, the list of ciphers, the list of Client CAs,
152 the certificates and keys.
154 .IX Header "WARNINGS"
155 If a session-remove callback is set (\fISSL_CTX_sess_set_remove_cb()\fR), this
156 callback will be called for each session being freed from \fBctx\fR's
157 session cache. This implies, that all corresponding sessions from an
158 external session cache are removed as well. If this is not desired, the user
159 should explicitly unset the callback by calling
160 SSL_CTX_sess_set_remove_cb(\fBctx\fR, \s-1NULL\s0) prior to calling \fISSL_CTX_free()\fR.
162 .IX Header "RETURN VALUES"
163 \&\fISSL_CTX_free()\fR does not provide diagnostic information.
