C++ 如何创建在崩溃时重新启动的服务

我正在使用创建一个服务。该服务将再次正常运行，如果它发生崩溃，我想让Windows重新启动服务，如果它崩溃。我知道可以从下面的服务msc设置此设置

如何以编程方式配置服务，使其在发生崩溃时始终重新启动。

您希望在安装服务后调用。将第二个参数设置为

SERVICE\u CONFIG\u FAILURE\u ACTIONS

，并将的实例作为第三个参数传递，如下所示：

int numBytes = sizeof(SERVICE_FAILURE_ACTIONS) + sizeof(SC_ACTION);
std::vector<char> buffer(numBytes);

SERVICE_FAILURE_ACTIONS *sfa = reinterpret_cast<SERVICE_FAILURE_ACTIONS *>(&buffer[0]);
sfa.dwResetPeriod = INFINITE;
sfa.cActions = 1;
sfa.lpsaActions[0].Type = SC_ACTION_RESTART;
sfa.lpsaActions[0].Delay = 5000; // wait 5 seconds before restarting

ChangeServiceConfig2(hService, SERVICE_CONFIG_FAILURE_ACTIONS, sfa);

int numBytes=sizeof（服务失败动作）+sizeof（服务失败动作）；
std：：向量缓冲区（单位：字节）；
服务失败动作*sfa=重新解释强制转换（&buffer[0]）；
sfa.dwResetPeriod=无限期；
sfa.cActions=1；
sfa.lpsaActions[0]。Type=SC\u ACTION\u RESTART；
sfa.LPSA操作[0]。延迟=5000；//等待5秒钟后再重新启动
ChangeServiceConfig2（hs服务、服务配置、故障操作、sfa）；

以上答案将为您提供要点。。。但它不会编译

尝试：

使用了Deltanine的方法，但对其进行了一些修改，以便能够控制每个故障动作：

SERVICE_FAILURE_ACTIONS servFailActions;
SC_ACTION failActions[3];

failActions[0].Type = SC_ACTION_RESTART; //Failure action: Restart Service
failActions[0].Delay = 120000; //number of seconds to wait before performing failure action, in milliseconds = 2minutes
failActions[1].Type = SC_ACTION_RESTART;
failActions[1].Delay = 120000;
failActions[2].Type = SC_ACTION_NONE;
failActions[2].Delay = 120000;

servFailActions.dwResetPeriod = 86400; // Reset Failures Counter, in Seconds = 1day
servFailActions.lpCommand = NULL; //Command to perform due to service failure, not used
servFailActions.lpRebootMsg = NULL; //Message during rebooting computer due to service failure, not used
servFailActions.cActions = 3; // Number of failure action to manage
servFailActions.lpsaActions = failActions;

ChangeServiceConfig2(sc_service, SERVICE_CONFIG_FAILURE_ACTIONS, &servFailActions); //Apply above settings

SERVICE_FAILURE_ACTIONS servFailActions;
SC_ACTION failActions[3];

failActions[0].Type = SC_ACTION_RESTART; //Failure action: Restart Service
failActions[0].Delay = 120000; //number of seconds to wait before performing failure action, in milliseconds = 2minutes
failActions[1].Type = SC_ACTION_RESTART;
failActions[1].Delay = 120000;
failActions[2].Type = SC_ACTION_NONE;
failActions[2].Delay = 120000;

servFailActions.dwResetPeriod = 86400; // Reset Failures Counter, in Seconds = 1day
servFailActions.lpCommand = NULL; //Command to perform due to service failure, not used
servFailActions.lpRebootMsg = NULL; //Message during rebooting computer due to service failure, not used
servFailActions.cActions = 3; // Number of failure action to manage
servFailActions.lpsaActions = failActions;

ChangeServiceConfig2(sc_service, SERVICE_CONFIG_FAILURE_ACTIONS, &servFailActions); //Apply above settings
