- * rtems_port_external_to_internal
- *
- * This directive converts an external dual-ported memory address to an
- * internal dual-ported memory address. If the given external address
- * is an invalid dual-ported address, then the internal address is set
- * to the given external address.
- *
- * Input parameters:
- * id - id of dp memory object
- * external - external address
- * internal - pointer of internal address to set
- *
- * Output parameters:
- * internal - internal address
- * RTEMS_SUCCESSFUL - always succeeds
