NAME    [Toc]    [Back]

       SSL_set_fd - connect the SSL object with a file descriptor

LIBRARY    [Toc]    [Back]

       libcrypto, -lcrypto

SYNOPSIS    [Toc]    [Back]

        #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);

DESCRIPTION    [Toc]    [Back]

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

       When performing the operation, a socket 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
       different).

       SSL_set_rfd() and SSL_set_wfd() perform the respective
       action, but only for the read channel or the write channel,
 which can be set independently.

RETURN VALUES    [Toc]    [Back]

       The following return values can occur:

       0   The operation failed. Check the error stack to find
           out why.

       1   The operation succeeded.
