+=head1 NAME
+
+SSL_set_bio, SSL_set0_rbio, SSL_set0_wbio - connect the SSL object with a BIO
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ void SSL_set_bio(SSL *ssl, BIO *rbio, BIO *wbio);
+ void SSL_set0_rbio(SSL *s, BIO *rbio);
+ void SSL_set0_wbio(SSL *s, BIO *wbio);
+
+=head1 DESCRIPTION
+
+SSL_set0_rbio() connects the BIO B<rbio> for the read operations of the B<ssl>
+object. The SSL engine inherits the behaviour of B<rbio>. If the BIO is
+non-blocking then the B<ssl> object will also have non-blocking behaviour. This
+function transfers ownership of B<rbio> to B<ssl>. It will be automatically
+freed using L<BIO_free_all(3)> when the B<ssl> is freed. On calling this
+function, any existing B<rbio> that was previously set will also be freed via a
+call to L<BIO_free_all(3)> (this includes the case where the B<rbio> is set to
+the same value as previously).
+
+SSL_set0_wbio() works in the same as SSL_set0_rbio() except that it connects
+the BIO B<wbio> for the write operations of the B<ssl> object. Note that if the
+rbio and wbio are the same then SSL_set0_rbio() and SSL_set0_wbio() each take
+ownership of one reference. Therefore it may be necessary to increment the
+number of references available using L<BIO_up_ref(3)> before calling the set0
+functions.
+
+SSL_set_bio() does a similar job as SSL_set0_rbio() and SSL_set0_wbio() except
+that it connects both the B<rbio> and the B<wbio> at the same time. This
+function transfers the ownership of B<rbio> and B<wbio> to B<ssl> except that
+the rules for this are much more complex. For this reason this function is
+considered a legacy function and SSL_set0_rbio() and SSL_set0_wbio() should be
+used in preference. The ownership rules are as follows:
+
+=over 2

+=item *
+
+If neither the rbio or wbio have changed from their previous values then nothing
+is done.
+
+=item *
+
+If the rbio and wbio parameters are different and both are different to their
+previously set values then one reference is consumed for the rbio and one
+reference is consumed for the wbio.
+
+=item *
+
+If the rbio and wbio parameters are the same and the rbio is not the same as the
+previously set value then one reference is consumed.
+
+=item *
+
+If the rbio and wbio parameters are the same and the rbio is the same as the
+previously set value, then no additional references are consumed.
+

+
+If the rbio and wbio parameters are different and the rbio is the same as the
+previously set value then one reference is consumed for the wbio and no
+references are consumed for the rbio.
+
+=item *
+
+If the rbio and wbio parameters are different and the wbio is the same as the
+previously set value and the old rbio and wbio values were the same as each
+other then one reference is consumed for the rbio and no references are consumed
+for the wbio.
