— Function: Autobuf * abuf_create ()

Uses ‘mem_alloc’ to allocate enough memory to store an Autobuf and initialises that memory as an empty autobuf. Returns a reference to the allocated darray, or a null pointer if there was insufficient memory.

— Function: void abuf_destroy (Autobuf *abuf)

Finalises abuf in the same way as ‘abuf_finalise’, and then frees the memory referenced by abuf. abuf must have been allocated by ‘abuf_create’.
