6 Storage Functions
The EAPI defines one user storage area with a minimal size of 32 Byte.
6.1 Common Parameters
6.1.1 Storage Ids
The EAPI only defines one user storage area. Additional vendor specific IDs are possible (see section
11 'Vendor Specific IDs' on page 76)
Id
EAPI_ID_STORAGE_STD
Description
Standard Storage Area >=32Bytes for read/write access
6.2 EApiStorageCap
6.2.1 Description
Get the capabilities of the selected storage area.
6.2.2 Parameters
Id
uint32_t
EAPI_CALLTYPE
EApiStorageCap(
__IN uint32_t Id , /* Storage Area Id */
__OUT uint32_t *pStorageSize , /* Total */
__OUT uint32_t *pBlockLength
);
FUNC_DEF 9: EApiStorageCap
__IN See '6.1.1 Storage Ids' on page 28
/* Write Block Length
* & Alignment
*/
pStorageSize
__OUTOPT Pointer to a buffer that receives storage area size. This parameter can be NULL if the
data is not required.
pBlockLength
__OUTOPT Pointer to a buffer that receives the the storage areas alignment/Block size. This
parameter can be NULL if the data is not required. The value must be used to calculate write block
alignment and size.
