Types

struct typeadapt_impl_t

typedef struct typeadapt_impl_t typeadapt_impl_t

Export typeadapt_impl_t into global namespace.

Functions

Summary
test
unittest_ds_typeadapt_typeadaptimplTest typeadapt_impl_t functionality.

test

unittest_ds_typeadapt_typeadaptimpl

int unittest_ds_typeadapt_typeadaptimpl(void)

Test typeadapt_impl_t functionality.

typeadapt_impl_t

struct typeadapt_impl_t

Default implementation of typeadapt_t.

Assumptions

1.  This implementation assumes that objects can be copied with a simple call to memcpy and no special deep copy semantic is needed.  2. The second one is that objects always have the same size.

Both assumptions are too simple for supporting complex object types.  But for complex objects it is considered OK to implement their own typeadapt_t*.

Summary

lifetime_deleteobj_typeadaptimplImplements typeadapt_lifetime_it.delete_object.

objectsize

size_t objectsize

The size of supported structure.

lifetime

typeadapt_impl_FREE

#define typeadapt_impl_FREE { typeadapt_FREE, 0 }

Static initializer.

typeadapt_impl_INIT

#define typeadapt_impl_INIT(
   objectsize
) { typeadapt_INIT_LIFETIME(&lifetime_newcopyobj_typeadaptimpl, &lifetime_deleteobj_typeadaptimpl), objectsize }

Static initializer.

init_typeadaptimpl

int init_typeadaptimpl(/*out*/typeadapt_impl_t *typeadp,
size_t objectsize)

Initializes implementation to support objectes of size objectsize.

free_typeadaptimpl

int free_typeadaptimpl(typeadapt_impl_t *typeadp)

Sets all fields to 0.  No additional resources are held.  Memory of objects which are not freed is kept intact.
