MirOS Manual: BIO_s_null(3)

BIO_S_NULL(3)                OpenSSL                BIO_S_NULL(3)


     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.
