NAME
       gnutls_hash_copy - API function


SYNOPSIS
       #include <gnutls/crypto.h>

       gnutls_hash_hd_t gnutls_hash_copy(gnutls_hash_hd_t handle);


ARGUMENTS
       gnutls_hash_hd_t handle
                   is a gnutls_hash_hd_t type


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


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


SINCE
       3.6.9
