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 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.
