分享Windows下写一个定时中断的程序，用MinGW编译
找到一个时钟中断的例子，http://blog.csdn.net/sunrier/article/details/6440029用minGW编译老是出现 error: variable or field 'interrupt' declared void的错误，编译不过去，是为什么啊？
我现在需要写一个时钟中断的程序，定时触发回调函数进行一些操作，类似于SetTimer或Linux下的setitimer函数，但必须是用MinGW编译通过，大神们给点启发吧

已解决 示例时钟
#include <Windows.h>

void CALLBACK TimeProc(
UINT uID,

int flag = 0;
int main(int argc, _TCHAR* argv[])

//回调过程(时钟到来,回调函数被系统自动调用)

cygwin是不是比mingw稳定些啊？功能差不多？？

mingw在windows下不稳定， 技术支持也不及时， 不建议在生产环境中使用。

不支持 interrupt 关键字的编译器,中断例程,用汇编语言实现吧
因为中断函数确实不同于 一般函数,
中断函数 用 iret 指令返回,
一般函数映 ret 指令返回
另外,一般现代操作系统,已经不支持直接的硬件操作了(包括中断),要编写中断服务程序,硬件支持程序,
一般来说,要编写 硬件驱动程序才可以

可以用cygwin阿 同样提供linux平台下的for win32的gcc,make等等

你没赶脚我2楼的代码Windows和Linux通吃吗？

首先Linux下的一些库，比如sys/time.h，windows下没有啊？那在linux下用的setitimer函数Windows下怎么用

MinGW不是号称在Windows下完全兼容Linux吗？
在Linux下怎么做就在MinGW下怎么做。
