跟踪嵌入式Python解释器中的代码执行

我想创建一个带有嵌入式python解释器和基本调试功能的应用程序.现在我在API中搜索可​​用于逐步运行代码的函数,并获取正在(或即将执行)的当前代码行的编号.

在进行跟踪和分析时,官方Python文档对我来说似乎有点不足.例如,没有关于返回值含义的信息Py_tracefunc.

到目前为止,我已经汇总了以下内容:

#include 

static int lineCounter = 0;

int trace(PyObject *obj, PyFrameObject *frame, int what, PyObject *arg)
{
    if(what == PyTrace_LINE)
    {
        lineCounter += 1;
        printf("line %d\n", lineCounter);
    }
    return 0;
}

int main(int argc, char *argv[])
{
    wchar_t *program = Py_DecodeLocale(argv[0], NULL);
    if (program == NULL) {
        fprintf(stderr, "Fatal error: cannot decode argv[0]\n");
        exit(1);
    }
    Py_SetProgramName(program);  /* optional but recommended */
    Py_Initialize();
    PyEval_SetTrace(trace, NULL);
    char *code = "def adder(a, b):\n"
                 " return a + b\n"
                 "x = 3\n"
                 "y = 4\n"
                 "print(adder(x, y))\n";
    PyRun_SimpleString(code);
    Py_Finalize();
    PyMem_RawFree(program);
    return 0;
}

但是,编译器输出以下错误:

hello.c:5:26: error: unknown type name ‘PyFrameObject’
 int trace(PyObject *obj, PyFrameObject *frame, int what, PyObject *arg)
                          ^
