  2. =head1 NAME
  3. BIO_f_null - null filter
  4. =head1 SYNOPSIS
  5. #include <openssl/bio.h>
  6. const BIO_METHOD *BIO_f_null(void);
  7. =head1 DESCRIPTION
  8. BIO_f_null() returns the null filter BIO method. This is a filter BIO
  9. that does nothing.
  10. All requests to a null filter BIO are passed through to the next BIO in
  11. the chain: this means that a BIO chain containing a null filter BIO
  12. behaves just as though the BIO was not there.
  13. =head1 NOTES
  14. As may be apparent a null filter BIO is not particularly useful.
  15. =head1 RETURN VALUES
  16. BIO_f_null() returns the null filter BIO method.
