NAME
       gnutls_hmac_copy - API function


SYNOPSIS
       #include <gnutls/crypto.h>

       gnutls_hmac_hd_t gnutls_hmac_copy(gnutls_hmac_hd_t handle);


ARGUMENTS
       gnutls_hmac_hd_t handle
                   is a gnutls_hmac_hd_t type


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


RETURNS
       new MAC context or NULL in case of an error.


SINCE
       3.6.9
