+* Functions that initialize an already allocated structure should be suffixed
+  with ``_init`` and take the structure to initialize as the first argument,
+  e.g., ``struct drgn_error *foo_init(struct foo *foo, int foo_flags)``.
+* The matching function to deinitialize a structure should be suffixed with
+  ``_deinit``, e.g., ``void foo_deinit(struct foo *foo)``. If possible, the
+  definition should be placed directly after the definition of ``_init`` so
+  that it is easier to visually verify that everything is cleaned up.
+* Functions that allocate and initialize a structure should be suffixed with
+  ``_create`` and either return the structure as an out parameter (e.g.,
+  ``struct drgn_error *foo_create(int foo_flags, struct foo **ret)``) or as the
+  return value if they can only fail with an out-of-memory error (e.g.,
+  ``struct foo *foo_create(int foo_flags)``).
+* The matching function to free an allocated structure should be suffixed with
+  ``_destroy``, e.g., ``void foo_destroy(struct foo *foo)``. If possible, the
+  definition should be placed directly after the definition of ``_create``.
+  ``_destroy`` should usually allow a ``NULL`` argument, just like ``free()``.
+* Functions that return a result in a ``struct drgn_object *`` parameter should
