win32下的SetTimer()无窗口调用方式

#include <stdio.h>
#include <windows.h>
#define IDT_TIMER 100

void CALLBACK TimerProc(HWND hwnd,UINT uMsg,UINT_PTR idEvent,DWORD dwTime)
{
SYSTEMTIME st;
GetLocalTime(&st);
printf("%2d:%2d:%2d.%3d hello!/n", st.wHour, st.wMinute, st.wSecond, st.wMilliseconds);
}
int main(int argc, char* argv[])
{
int iret = SetTimer(NULL, IDT_TIMER, 1000, (TIMERPROC)TimerProc);
MSG msg;
while (1)
{
GetMessage(&msg, NULL, 0, 0);
DispatchMessage(&msg);
}
return 0;
}
