NAME
SSL_set_fd, SSL_set_rfd, SSL_set_wfd - connect the SSL object with a
file descriptor
LIBRARY
libcrypto, -lcrypto
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.
