BIO_s_null(3)                OpenSSL                BIO_s_null(3)



NAME

       BIO_s_null - null data sink


LIBRARY

       libcrypto, -lcrypto


SYNOPSIS

        #include <openssl/bio.h>

        BIO_METHOD *   BIO_s_null(void);



DESCRIPTION

       BIO_s_null() returns the null sink BIO method. Data writ-
       ten 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.
