#define REGION_INFORMATION_DEFINE | ( | max | ) |
Macro to define the objects information for the Classic Region objects.
This macro should only be used by <rtems/confdefs.h>.
max | The configured object maximum (the OBJECTS_UNLIMITED_OBJECTS flag may be set). |
RTEMS_INLINE_ROUTINE Region_Control* _Region_Allocate | ( | void | ) |
Region_Allocate.
This function allocates a region control block from the inactive chain of free region control blocks.
RTEMS_INLINE_ROUTINE void* _Region_Allocate_segment | ( | Region_Control * | the_region, |
uintptr_t | size | ||
) |
Region_Allocate_segment.
This function attempts to allocate a segment from the_region. If successful, it returns the address of the allocated segment. Otherwise, it returns NULL.
RTEMS_INLINE_ROUTINE void _Region_Free | ( | Region_Control * | the_region | ) |
Region_Free.
This routine frees a region control block to the inactive chain of free region control blocks.
RTEMS_INLINE_ROUTINE bool _Region_Free_segment | ( | Region_Control * | the_region, |
void * | the_segment | ||
) |
Region_Free_segment.
This function frees the_segment to the_region.
void _Region_Process_queue | ( | Region_Control * | the_region | ) |
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.
[in] | the_region | is the the region |
