From 789f6bab849e04ea029c09b81dc8401dc0268cf9 Mon Sep 17 00:00:00 2001 From: Andrey Ignatov Date: Thu, 14 Feb 2019 15:01:43 -0800 Subject: libbpf: Introduce bpf_object__btf Add new accessor for bpf_object to get opaque struct btf * from it. struct btf * is needed for all operations with BTF and it's present in bpf_object. The only thing missing is a way to get it. Example use-case is to get BTF key_type_id and value_type_id for a map in bpf_object. It can be done with btf__get_map_kv_tids() but that function requires struct btf *. Similar API can be added for struct btf_ext but no use-case for it yet.
