SSL_set_fd(3) OpenSSL SSL_set_fd(3)NAMESSL_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);
DESCRIPTIONSSL_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.
