Function Documentation

void SFMCacheAddBlock	(	H_SfmInstance	sfm,
		U8BIT	size1,
		U8BIT	bknum,
		void **	phBuffer
	)

Allocates space in cache for section data If allocation is made, *phBuffer has holds cache location. If section already allocated, or insufficient space, then *phBuffer is NULL.

Parameters

H_SfmCache	cache SFM cache handle.
U8BIT	size1 header[1] byte with top bits for section size
void**	phBuffer Pointer to SFM cache filter handle and return param with pointer to node block

Returns

void.

Parameters

H_SfmInstance	sfm SFM instance handle.
H_CacheTable	ctable Cache table handle
void**	phBuffer Pointer to SFM section buffer handle

Returns

void.

void SFMCacheProcessSection	(	H_SfmInstance	sfm,
		U8BIT *	pSection,
		H_CacheFilter	cfilter
	)

Tells SFM Cache to update DSM-CC with cached buffer (reported to F_CacheMatch callback funtion. This also allows SFM cache to clean up completed buffers.

Parameters

H_SfmInstance	sfm SFM instance handle.
U8BIT*	pSection Pointer to whole section data buffer
H_CacheFilter	cfilter Hande given to F_CacheMatch

Returns

void.

H_CacheFilter SFMCacheRetrieveFilter	(	H_SfmInstance	sfm,
		H_CacheTable	ctable,
		U16BIT	teid,
		U8BIT	vers
	)

Search cache for section data.

Parameters

H_SfmCache	cache SFM cache handle.
H_CacheTable	ctable Cache table handle
U16BIT	teid Table Extension ID

Returns

H_CacheFilter

Definition at line 581 of file sfm_cache.c.

void SFMCacheSearch	(	H_SfmInstance	sfm,
		H_CacheTable	ctable,
		S_TableExt	tex,
		U16BIT	dsmref,
		E_SFM_STATUS	status
	)

Search cache for section data.

Parameters

H_SfmInstance	sfm SFM instance handle.
H_CacheTable	ctable Cache table handle
S_TableExt	tex Table Extension ID and mask

Returns

void.

Definition at line 822 of file sfm_cache.c.

BOOLEAN SFMCacheValidHandle	(	H_SfmInstance	sfm,
		void *	ptr
	)

Parameters

H_SfmInstance	sfm SFM instance handle.
void*	hCache Handle to cache buffer given to the F_CacheMatch callback function

Returns

BOOLEAN
