Macro Definition Documentation

REGION_INFORMATION_DEFINE

#define REGION_INFORMATION_DEFINE

(

max

)

Value:

OBJECTS_INFORMATION_DEFINE( \
  _Region, \
  OBJECTS_CLASSIC_API, \
  OBJECTS_RTEMS_REGIONS, \
  Region_Control, \
  max, \
  OBJECTS_NO_STRING_NAME, \
  NULL \
)

Macro to define the objects information for the Classic Region objects.

This macro should only be used by <rtems/confdefs.h>.

Parameters

max	The configured object maximum (the OBJECTS_UNLIMITED_OBJECTS flag may be set).

REGION_OF_THREAD_QUEUE_QUEUE

#define REGION_OF_THREAD_QUEUE_QUEUE

(

queue

)

Value:

RTEMS_CONTAINER_OF( queue, Region_Control, Wait_queue.Queue )

Function Documentation

_Region_Process_queue()

void _Region_Process_queue ( Region_Control * the_region )

extern

Process Region Queue.

This is a helper routine which is invoked any time memory is freed. It looks at the set of waiting tasks and attempts to satisfy all outstanding requests.

Parameters
