NAME         top

       gnutls_hmac_copy - API function

SYNOPSIS         top

       #include <gnutls/crypto.h>

       gnutls_hmac_hd_t gnutls_hmac_copy(gnutls_hmac_hd_t handle);

ARGUMENTS         top

       gnutls_hmac_hd_t handle
                   is a gnutls_hmac_hd_t type

DESCRIPTION         top

       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         top

       new MAC context or NULL in case of an error.

SINCE         top

       3.6.9
