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 (encrypted) side of ssl. fd will typically be the socket file descriptor of a network connection.

When performing the operation, a socket

is automatically created to interface between the ssl and fd. The and hence the engine inherit the behaviour of fd. If fd is non-blocking, the ssl will also have non-blocking behaviour.

If there was already a

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.
