null data sink
#include <openssl/bio.h>const BIO_METHOD *
BIO_s_null() returns the null sink BIO method. Data written to the null sink is discarded, reads return EOF. A null sink BIO behaves in a similar manner to the null(4) 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.
BIO_s_null() returns the null sink BIO method. BIO_new(3)
BIO_s_null() first appeared in SSLeay 0.6.0 and has been available since OpenBSD 2.4.
