gnutls_hash_copy(3)               gnutls              gnutls_hash_copy(3)

NAME         top

       gnutls_hash_copy - API function

SYNOPSIS         top

       #include <gnutls/crypto.h>

       gnutls_hash_hd_t gnutls_hash_copy(gnutls_hash_hd_t handle);

ARGUMENTS         top

       gnutls_hash_hd_t handle
                   is a gnutls_hash_hd_t type

DESCRIPTION         top

       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         top

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

SINCE         top

       3.6.9
