@deftypefun {int} {gnutls_pkcs11_obj_export} (gnutls_pkcs11_obj_t @var{obj}, void * @var{output_data}, size_t * @var{output_data_size})
@var{obj}: Holds the object

@var{output_data}: will contain the object data

@var{output_data_size}: holds the size of output_data (and will be
replaced by the actual size of parameters)

This function will export the PKCS11 object data.  It is normal for
data to be inaccessible and in that case @code{GNUTLS_E_INVALID_REQUEST} 
will be returned.

If the buffer provided is not long enough to hold the output, then
*output_data_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will
be returned.

@strong{Returns:} In case of failure a negative error code will be
returned, and @code{GNUTLS_E_SUCCESS}  (0) on success.

@strong{Since:} 2.12.0
