SSL_CTX_FREE(3) FreeBSD Library Functions Manual SSL_CTX_FREE(3) NAME SSL_CTX_free - free an allocated SSL_CTX object SYNOPSIS #include <openssl/ssl.h> void SSL_CTX_free(SSL_CTX *ctx); DESCRIPTION SSL_CTX_free() decrements the reference count of ctx, and removes the SSL_CTX object pointed to by ctx and frees up the allocated memory if the reference count has reached 0. If ctx is a NULL pointer, no action occurs. It also calls the free(3)ing procedures for indirectly affected items, if applicable: the session cache, the list of ciphers, the list of Client CAs, the certificates and keys. WARNINGS If a session-remove callback is set (SSL_CTX_sess_set_remove_cb(3)), this callback will be called for each session being freed from ctx's session cache. This implies that all corresponding sessions from an external session cache are removed as well. If this is not desired, the user should explicitly unset the callback by calling SSL_CTX_sess_set_remove_cb(ctx, NULL) prior to calling SSL_CTX_free().
