The first two of these allow you to get function type info and args out of the types section give a type ID: astonishingly, this was missing from libctf before now: so even though types of kind CTF_K_FUNCTION were supported, you couldn't find out anything about them. (The existing ctf_func_info and ctf_func_args only allow you to get info about functions in the function section, i.e. given symbol table indexes, not type IDs.) The second of these allows you to get the raw undecorated name out of the CTF section (strdupped for safety) without traversing subtypes to build a full C identifier out of it. It's useful for things that are already tracking the type kind etc and just need an unadorned name. include/ * ctf-api.h (ECTF_NOTFUNC): Fix description. (ctf_func_type_info): New.

strtab construction.
