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 dis-
       card 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.
