StorageGetSize()

type

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

Return values

size	size 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

Here is the caller graph for this function:

StorageRegister()

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

Register new storage.

Parameters

type	type from StorageEnum
name	name
size	size of the per instance storage
Alloc	alloc function for per instance storage
Free	free 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.
