SSL_set_fd(3)                       OpenSSL                      SSL_set_fd(3)

       SSL_set_fd - connect the SSL object with a file(1,n) descriptor

        #include <openssl/ssl.h>

        int SSL_set_fd(SSL *ssl, int fd);
        int SSL_set_rfd(SSL *ssl, int fd);
        int SSL_set_wfd(SSL *ssl, int fd);

       SSL_set_fd() sets the file(1,n) descriptor fd as the input/output facility
       for the TLS/SSL (encrypted) side of ssl. fd will typically be the
       socket(2,7,n) file(1,n) descriptor of a network connection.

       When performing the operation, a socket(2,7,n) BIO is automatically created to
       interface between the ssl and fd. The BIO and hence the SSL engine
       inherit the behaviour of fd. If fd is non-blocking, the ssl will also
       have non-blocking behaviour.

       If there was already a BIO connected to ssl, BIO_free() will be called
       (for both the reading and writing side, if(3,n) different).

       SSL_set_rfd() and SSL_set_wfd() perform the respective action, but only
       for the read(2,n,1 builtins) channel or the write(1,2) channel, which can be set(7,n,1 builtins) indepen-

       The following return values can occur:

       0   The operation failed. Check the error(8,n) stack to find out why.

       1   The operation succeeded.
