NAME    [Toc]    [Back]

       BIO_s_null - Null data sink

SYNOPSIS    [Toc]    [Back]

       #include <openssl/bio.h>

       BIO_METHOD *   BIO_s_null(
               void );

DESCRIPTION    [Toc]    [Back]

       BIO_s_null()  returns the null sink BIO method. Data written
 to the null sink is discarded; reads return EOF.

NOTES    [Toc]    [Back]

       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    [Toc]    [Back]
