SSL_SET_FD(3)			    OpenSSL			 SSL_SET_FD(3)

NAME
       SSL_set_fd, SSL_set_rfd,	SSL_set_wfd - 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 nonblocking, the ssl will also
       have nonblocking	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.
