MCO_RET mco_uda_to_mco( /*IN*/ mco_uda_object_handle_t * udaobj, /*OUT*/ MCO_Hf * ret );
udaobj | Handle of a UDA object |
ret |
The address of a variable to receive the "native" database object handle |
This function makes a “native” object handle from a UDA object handle. This can be useful when it is necessary to mix UDA calls with native API calls that have no UDA counterpart, for example, XML functions.
MCO_S_OK | Object handle successfully returned |
MCO_E_UDA_STRUCT_NOT_CLASS | Invalid object handle |
