static PyObject * spam_system(PyObject *self, PyObject *args) { const char *command; int sts; if (!PyArg_ParseTuple(args, "s", &command)) return NULL; sts = system(command); return PyLong_FromLong(sts); } 可见改造成本非常高,所有的基本类型都必须手动改为CPython解释器封装的binding类型...
PyThreadState将它们维护为PyFrameObjects的堆栈。线程状态使用单个指针指向任何给定时间的最顶层帧。给定以上设置和TSS密钥,我们可以从本机线程开始,找到PyThreadState,然后“遍历堆栈”PyFrameObjects。 然而,事实比理论更加棘手一些。我们不能只是#include <Python.h>并调用相同的函数faulthandler:因为Crashpad的处理程序...
