/* Description
* Allocates an object of the type represented by 'local_type_id' in
* program BTF. User may use the bpf_core_type_id_local macro to pass the
* type ID of a struct in program BTF.
*
* The 'local_type_id' parameter must be a known constant.
* The 'meta' parameter is a hidden argument that is ignored.
* Returns
* A pointer to an object of the type corresponding to the passed in
* 'local_type_id', or NULL on failure.
