uftrace专门用来跟踪用户态的C/C++以及Rust程序的执行，此外它也支持跟踪内核函数。
前一篇文章bpf_func_id是如何产生的？是以minimal为例，下面用uftrace跟踪一下执行流。为了可以让uftrace更好的工作，需要对Makefile稍加修改，给GCC加入-pg编译选项，用GCC编译的程序是bpf的用户态程序以及libbpf库，下面是修改方法：
对examples/c/Makefile的修改
diff --git a/examples/c/Makefile b/examples/c/Makefile

修改完毕后，clean掉然后重新编译。
用uftrace进行跟踪，同时-a开启自动探测函数参数以及返回值的功能：
# uftrace record -a --no-event ./minimal
# uftrace replay
下面是输出的日志：
