int gnutls_ia_allocate_client_credentials(gnutls_ia_client_credentials_t * sc);
gnutls_ia_client_credentials_t * sc
is a pointer to a gnutls_ia_server_credentials_t structure.
This structure is complex enough to manipulate directly thus this
helper function is provided in order to allocate it.
Adding this credential to a session will enable TLS/IA, and will
require an Application Phase after the TLS handshake (if the server

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise
an error code is returned.
