◆ StorageGetSize()

unsigned int StorageGetSize ( StorageEnum  type)

get the size of the void array used to store the pointers

Return values
sizesize in bytes, can return 0 if not storage is needed
Todo:
we could return -1 when registration isn't closed yet, however this will break lots of tests currently, so not doing it now

◆ StorageRegister()

int StorageRegister ( const StorageEnum  type,
const char *  name,
const unsigned int  size,
void *(*)(unsigned int)  Alloc,
void(*)(void *)  Free 
)

Register new storage.

Parameters
typetype from StorageEnum
namename
sizesize of the per instance storage
Allocalloc function for per instance storage
Freefree function for per instance storage
Note
if size == ptr size (so sizeof(void *)) and Alloc == NULL the API just gives the caller a ptr to store something it alloc'ed itself.
