I prefer to actually have flags here and not a single integer value. So I would use this: #define RTEMS_MM_REGION_BIT_READ 0 #define RTEMS_MM_REGION_BIT_WRITE 1 #define RTEMS_MM_REGION_BIT_EXECUTE 2 #define RTEMS_MM_REGION_BIT_CACHE 3 #define RTEMS_MM_REGION_BIT_DEVICE 4 #define RTEMS_MM_REGION_BIT_SHARED 5 #define RTEMS_MM_REGION_READ (1U << RTEMS_MM_REGION_BIT_WRITE) etc. This can be used to get architecture specific values easily: ((flags >> RTEMS_MM_REGION_BIT_READ) & 0x1U) << ARCH_READ_SHIFT -- Sebastian Huber, embedded brains GmbH Address : Dornierstr. 4, D-82178 Puchheim, Germany Phone : +49 89 189 47 41-16 Fax : +49 89 189 47 41-09 E-Mail : sebastian.hu...@embedded-brains.de PGP : Public key available on request.
