SSL_set_fd(3)                                OpenSSL                                SSL_set_fd(3)



NAME
       SSL_set_fd - connect the SSL object with a file descriptor

SYNOPSIS
        #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
       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
       The following return values can occur:

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

       1   The operation succeeded.
