NAME
BIO_s_null - null data sink
SYNOPSIS
Header "SYNOPSIS" .Vb 1
#include <openssl/bio.h>
\&
const BIO_METHOD *BIO_s_null(void);
.Ve
DESCRIPTION
Header "DESCRIPTION" \fBBIO_s_null() returns the null sink BIO method. Data written to
the null sink is discarded, reads return EOF.
NOTES
Header "NOTES" A null sink BIO behaves in a similar manner to the Unix /dev/null
device.
A null bio can be placed on the end of a chain to discard any data passed through it.
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
"RETURN VALUES"
Header "RETURN VALUES" \fBBIO_s_null() returns the null sink BIO method.
