From 0ac6231298cbc5a3a16bd4e98d85d98700b81dee Mon Sep 17 00:00:00 2001 From: Nick Alcock Date: Sat, 13 Jul 2019 20:00:07 +0100 Subject: [PATCH] libctf: Add iteration over non-root types The existing function ctf_type_iter lets you iterate over root-visible types (types you can look up by name). There is no way to iterate over non-root-visible types, which is troublesome because both the linker and dumper want to do that. So add a new function that can do it: the callback it takes accepts an extra parameter which indicates whether the type is root-visible or not. include/ * ctf-api.h (ctf_type_all_f): New.
