# NAME

SSL_set_bio - connect the SSL object with a BIO

# SYNOPSIS

     #include <openssl/ssl.h>

     void SSL_set_bio(SSL *ssl, BIO *rbio, BIO *wbio);

# DESCRIPTION

`SSL_set_bio()` connects the BIOs rbio and wbio for the read and write operations of the TLS/SSL (encrypted) side of ssl.

The SSL engine inherits the behaviour of rbio and wbio, respectively. If a BIO 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).

# RETURN VALUES

`SSL_set_bio()` cannot fail.
