BOOL WINAPI StartService(_In_ SC_HANDLE hService,_In_ DWORD dwNumServiceArgs,_In_opt_ LPCTSTR *lpServiceArgVectors);
函数作用：开始一个服务
参数：
2. dwNumServiceArgs：下一个形参lpServiceArgVectors的字符串个数，如果lpServiceArgVectors为空，那么该参数设为0
3. lpServiceArgVectors：传递给服务ServiceMain的参数，如果没有，可以设为NULL；否则，第一个形参lpServiceArgVectors[0]为服务的名字，其他则为需要传入的参数。
注意：驱动不接受这些参数，即lpServiceArgVectors为空，dwNumServiceArgs为0
返回值：
成功，非0；失败为0，错误码可以通过GetLastError获得；
| Return code | Description |
|---|
- ERROR_ACCESS_DENIED
|
The handle does not have the SERVICE_START access right.
|
- ERROR_INVALID_HANDLE
|
The handle is invalid.
|
- ERROR_PATH_NOT_FOUND
|
The service binary file could not be found.
|
- ERROR_SERVICE_ALREADY_RUNNING
|
An instance of the service is already running.
|
- ERROR_SERVICE_DATABASE_LOCKED
|
The database is locked.
|
- ERROR_SERVICE_DEPENDENCY_DELETED
|
The service depends on a service that does not exist or has been marked for deletion.
|
- ERROR_SERVICE_DEPENDENCY_FAIL
|
The service depends on another service that has failed to start.
|
- ERROR_SERVICE_DISABLED
|
The service has been disabled.
|
- ERROR_SERVICE_LOGON_FAILED
|
The service did not start due to a logon failure. This error occurs if the service is configured to run under an account that does not have the "Log on as a service" right.
|
- ERROR_SERVICE_MARKED_FOR_DELETE
|
The service has been marked for deletion.
|
- ERROR_SERVICE_NO_THREAD
|
A thread could not be created for the service.
|
- ERROR_SERVICE_REQUEST_TIMEOUT
|
The process for the service was started, but it did not call StartServiceCtrlDispatcher, or the thread that called StartServiceCtrlDispatcher may be blocked in a control handler function.

说明：
（1）当启动的是驱动服务，那么直到该驱动服务初始化完毕，StartService才返回
（2）如果必须的话，启动一个服务时SCM会产生一个服务进程。如果启动的服务和其他服务共享一个进程，那么所需要的进程可能已经存在，则SCM不需要再另外创建进程了。
StartService不会等待更新自服务的第一个状态，因为这需要一段时间。然而，当SCM从服务控制调度程序那里接收到ServiceMain服务线程已经创建成功的通知，则StartService将会返回。（3）在StartService返回前，SCM将会设置一下默认值：
- 当前服务的状态设为SERVICE_START_PENDING
- 接收的控制（Controls accepted）设为0
- CheckPoint变量设为0
- WaitHint时间值设为2s
（4）调用的程序能够定期地调用
QueryServiceStatus函数获取服务的状态，判断新服务是否完成了初始化
（5）一个服务在初始化期间不能调用StartService，因为初始化期间，SCM会锁定SCM数据库，所以StartService会被暂停。当一个服务通知SCM已经初始化完成，那么该服务可以调用StartService
（6）和ControlService一样，如果其他服务正忙于处理控制码，StartService也有一个超时时间30s。如果忙于处理控制码的服务没有在30s内从它的处理函数返回，那么StartService将调用失败，返回ERROR_SERVICE_REQUEST_TIMEOUT，这是因为SCM一次只能处理一个服务控制通知。
