Data written to the null sink is discarded, reads return EOF.</p> <h1 id="NOTES">NOTES</h1> <p>A null sink BIO behaves in a similar manner to the Unix /dev/null device.</p> <p>A null bio can be placed on the end of a chain to discard any data passed through it.</p> <p>A null sink is useful if, for example, an application wishes to digest some data by writing through a digest bio but not send the digested data anywhere. Since a BIO chain must normally include a source/sink BIO this can be achieved by adding a null sink BIO to the end of the chain</p> <h1 id="RETURN-VALUES">RETURN VALUES</h1> <p>BIO_s_null() returns the null sink BIO method.</p> <h1 id="COPYRIGHT">COPYRIGHT</h1> <p>Copyright 2000-2016 The OpenSSL Project Authors.
