BIO_s_null(3)                                OpenSSL                                BIO_s_null(3)



NAME
       BIO_s_null - null data sink

SYNOPSIS
        #include <openssl/bio.h>

        BIO_METHOD *   BIO_s_null(void);

DESCRIPTION
       BIO_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 VALUES
       BIO_s_null() returns the null sink BIO method.
