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

Function Documentation

◆ _Region_Allocate()

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.

◆ _Region_Allocate_segment()

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.

◆ _Region_Free()

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.

◆ _Region_Free_segment()

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.

◆ _Region_Process_queue()

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.

Parameters

[in] the_region is the the region
