c - 如何检查Windows文件索引打开还是关闭

C中是否有API可用于检查文件索引打开还是关闭？
代码受到赞赏。

最佳答案

WMI在C ++中很痛苦，但是本机Service API非常干净。

SC_HANDLE hSCManager = OpenSCManager(NULL, NULL, SC_MANAGER_CONNECT);
if(hSCManager)
{
    SC_HANDLE hService = OpenService(hSCManager, _T("ServiceNameGoesHere"), SERVICE_QUERY_STATUS);
    if(hService)
    {
        // service is installed
        SERVICE_STATUS ServiceStatus;
        if(ServiceQueryStatus(hService, &ServiceStatus))
        {
            // service is running
            // get current state from ServiceStatus.dwCurrentState
        }
        else if(GetLastError() == ERROR_SERVICE_NOT_ACTIVE)
        {
            // service is not running
        }
        else
        {
            // error
        }
        CloseServiceHandle(hService);
        hService = NULL;
    }
    else if(GetLastError() == ERROR_SERVICE_DOES_NOT_EXIST)
    {
        // service is not installed
    }
    else
    {
        // error
    }
    CloseServiceHandle(hSCManager);
    hSCManager = NULL;
}
else
{
    // error
}
