SSL_GET_FD(3)			    OpenSSL			 SSL_GET_FD(3)

NAME
       SSL_get_fd, SSL_get_rfd,	SSL_get_wfd - 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.
