131 .IX Title "SSL_free 3"
132 .TH SSL_free 3 "2006-11-19" "0.9.8d" "OpenSSL"
134 SSL_free \- free an allocated SSL structure
136 .IX Header "SYNOPSIS"
138 \& #include <openssl/ssl.h>
142 \& void SSL_free(SSL *ssl);
145 .IX Header "DESCRIPTION"
146 \&\fISSL_free()\fR decrements the reference count of \fBssl\fR, and removes the \s-1SSL\s0
147 structure pointed to by \fBssl\fR and frees up the allocated memory if the
148 the reference count has reached 0.
151 \&\fISSL_free()\fR also calls the \fIfree()\fRing procedures for indirectly affected items, if
152 applicable: the buffering \s-1BIO\s0, the read and write BIOs,
153 cipher lists specially created for this \fBssl\fR, the \fB\s-1SSL_SESSION\s0\fR.
154 Do not explicitly free these indirectly freed up items before or after
155 calling \fISSL_free()\fR, as trying to free things twice may lead to program
158 The ssl session has reference counts from two users: the \s-1SSL\s0 object, for
159 which the reference count is removed by \fISSL_free()\fR and the internal
160 session cache. If the session is considered bad, because
161 \&\fISSL_shutdown\fR\|(3) was not called for the connection
162 and \fISSL_set_shutdown\fR\|(3) was not used to set the
163 \&\s-1SSL_SENT_SHUTDOWN\s0 state, the session will also be removed
164 from the session cache as required by \s-1RFC2246\s0.
166 .IX Header "RETURN VALUES"
167 \&\fISSL_free()\fR does not provide diagnostic information.
