BIO_s_null - null data sink
#include <openssl/bio.h>
BIO_METHOD * BIO_s_null(void);
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 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 nor-
mally 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.
