BIO_s_null(3) OpenSSL BIO_s_null(3)NAMEBIO_s_null - null data sink
SYNOPSIS
#include <openssl/bio.h>
BIO_METHOD * BIO_s_null(void);
DESCRIPTIONBIO_s_null() returns the null sink BIO method. Data
written to the null sink is discarded, reads return EOF.
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 VALUESBIO_s_null() returns the null sink BIO method.
