求一使用SetWaitableTimer的具体例子

[King_Dragon]

如题。

没用过，信号量和临界区倒是用过。

#include <windows.h>
#include <stdio.h>

int main()
{
HANDLE hTimer = NULL;
LARGE_INTEGER liDueTime;

liDueTime.QuadPart=-100000000;

// Create a waitable timer.
hTimer = CreateWaitableTimer(NULL, TRUE, "WaitableTimer");
if (!hTimer)
{
printf("CreateWaitableTimer failed (%d)\n", GetLastError());
return 1;
}

printf("Waiting for 10 seconds...\n");

// Set a timer to wait for 10 seconds.
if (!SetWaitableTimer(
hTimer, &liDueTime, 0, NULL, NULL, 0))
{
printf("SetWaitableTimer failed (%d)\n", GetLastError());
return 2;
}

// Wait for the timer.

if (WaitForSingleObject(hTimer, INFINITE) != WAIT_OBJECT_0)
printf("WaitForSingleObject failed (%d)\n", GetLastError());
else printf("Timer was signaled.\n");

return 0;
}
