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.
