Libbpf userspace function btf__new_empty
Creates an empty BTF object. Use btf__add_*() to populate such BTF object.
Definition
struct btf *btf__new_empty(void);
Return
New BTF object instance which has to be eventually freed with btf__free()
On error, error-code-encoded-as-pointer is returned, not a NULL. To extract error code from such a pointer libbpf_get_error should be used. If libbpf_set_strict_mode(LIBBPF_STRICT_CLEAN_PTRS) is enabled, NULL is returned on error instead. In both cases thread-local errno variable is always set to error code as well.
