DESCRIPTION

18       This  function will create a copy of Message Digest context, containing
19       all its current state. Copying contexts for Message Digests  registered
20       using  gnutls_crypto_register_digest() is not supported and will always
21       result in an error. In addition to that, some of the Message Digest im‐
22       plementations  do not support this operation. Applications should check
23       the return value and provide a proper fallback.
24

RETURNS

26       new Message Digest context or NULL in case of an error.
