@deftypefun {int} {gnutls_pkcs11_copy_pubkey} (const char * @var{token_url}, gnutls_pubkey_t @var{pubkey}, const char * @var{label}, const gnutls_datum_t * @var{cid}, unsigned int @var{key_usage}, unsigned int @var{flags})
@var{token_url}: A PKCS @code{11}  URL specifying a token

@var{pubkey}: The public key to copy

@var{label}: The name to be used for the stored data

@var{cid}: The CKA_ID to set for the object -if NULL, the ID will be derived from the public key

@var{key_usage}: One of GNUTLS_KEY_*

@var{flags}: One of GNUTLS_PKCS11_OBJ_FLAG_*

This function will copy a public key object into a PKCS @code{11}  token specified by
a URL. Valid flags to mark the key: @code{GNUTLS_PKCS11_OBJ_FLAG_MARK_TRUSTED} ,
@code{GNUTLS_PKCS11_OBJ_FLAG_MARK_PRIVATE} , @code{GNUTLS_PKCS11_OBJ_FLAG_MARK_CA} ,
@code{GNUTLS_PKCS11_OBJ_FLAG_MARK_ALWAYS_AUTH} .

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error value.

@strong{Since:} 3.4.6
