Some review comments came in after I pushed the last lot of ctf-api.h comment improvements. They were good, so I've incorporated them. Mostly: better _next iterator usage info, better info on ctf_*open functions, and better info on ctf_type_aname and ctf_type_name_raw. include/ * ctf-api.h: improve documentation.

arg which must be the address of a variable whose value is NULL on first

call, and will be set to NULL again once iteration has completed.

They return something important about the thing being iterated over (often a

type ID or a name); on end of iteration they instead return return CTF_ERR,

|
-1, or NULL and set the error ECTF_NEXT_END on the dict. They can often

provide more information too: this is done via pointer parameters (e.g. the

|
membname and membtype in ctf_member_next()). These parameters are always

|
optional and can be set to NULL if not needed.

error to something other than ECTF_NEXT_END, and *not* destroy the iterator:
|
|
you should either recover somehow and continue iterating, or call

ctf_next_destroy() on it. (You can call ctf_next_destroy() on a NULL
