Function Documentation

_Region_Allocate()

static __inline__ Region_Control* _Region_Allocate ( void  )

static

Region_Allocate.

This function allocates a region control block from the inactive chain of free region control blocks.

Definition at line 47 of file regionimpl.h.

_Region_Allocate_segment()

static __inline__ void* _Region_Allocate_segment ( Region_Control *  the_region, uintptr_t  size  )

static

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.

Definition at line 97 of file regionimpl.h.

_Region_Free()

static __inline__ void _Region_Free ( Region_Control *  the_region )

static

Region_Free.

This routine frees a region control block to the inactive chain of free region control blocks.

Definition at line 58 of file regionimpl.h.

_Region_Free_segment()

static __inline__ bool _Region_Free_segment ( Region_Control *  the_region, void *  the_segment  )

static

Region_Free_segment.

This function frees the_segment to the_region.

Definition at line 110 of file regionimpl.h.

_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
