=head1 NAME
BIO_s_null - null data sink
=head1 SYNOPSIS
#include <openssl/bio.h>
BIO_METHOD * BIO_s_null(void);
=head1 DESCRIPTION
BIO_s_null() returns the null sink BIO method. Data written to
the null sink is discarded, reads return EOF.
=head1 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
=head1 RETURN VALUES
BIO_s_null() returns the null sink BIO method.
