# anv_trace
RT-Thread 程序追踪软件包，帮助定位程序运行位置。

    int anv_trace_example(int argc, char const *argv[])
    {
        anv_trace_init(stdout);

        anv_trace_enter();
        anv_traced("Hello %s!", "Debug");
        anv_tracei("Hello %s!", "Info");
        anv_tracew("Hello %s!", "Warning");
        anv_tracee("Hello %s!", "Error");
        anv_tracef("Hello %s!", "Fatal");
        anv_trace_leave();

        anv_trace_quit();

      return 0;
    }

可以知道程序什么时候进入了哪个函数，有没有顺利退出。
