SSL_get_fd(3SSL)						      OpenSSL							  SSL_get_fd(3SSL)

NAME

       SSL_get_fd - get file descriptor linked to an SSL object

SYNOPSIS

	#include <openssl/ssl.h>

	int SSL_get_fd(const SSL *ssl);
	int SSL_get_rfd(const SSL *ssl);
	int SSL_get_wfd(const SSL *ssl);

DESCRIPTION

       SSL_get_fd() returns the file descriptor which is linked to ssl.  SSL_get_rfd() and SSL_get_wfd() return the file descriptors for the read
       or the write channel, which can be different. If the read and the write channel are different, SSL_get_fd() will return the file descriptor
       of the read channel.

RETURN VALUES

       The following return values can occur:

       -1  The operation failed, because the underlying BIO is not of the correct type (suitable for file descriptors).

       >=0 The file descriptor linked to ssl.

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.
