C create and run windows service - c

Question

I am trying to create a service that will be run at system startup and start it immediately. Service is supposed to run my exe file.
GetLastError function return 1053 error code.
int main(void)
{
SC_HANDLE SC_manager_handle;
SC_HANDLE service_handle;
LPCTSTR binary_path = "C:\\Users\\User\\AppData\\file.exe";
LPCTSTR display_name = "ExampleService";
LPCTSTR service_name = "EXAMPLE_SERVICE";
SC_manager_handle = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
puts("-----------------------");
if(SC_manager_handle == NULL)
puts("Open SM Manager: FAILED");
else
puts("SC Manager: SUCCESS");
service_handle = CreateService(SC_manager_handle, service_name, display_name, SERVICE_ALL_ACCESS ,SERVICE_WIN32_OWN_PROCESS, SERVICE_AUTO_START, SERVICE_ERROR_NORMAL, binary_path, NULL, NULL, NULL, NULL, NULL);
if(service_handle == NULL)
puts("Create Service: FAILED");
else
puts("Service Create: SUCCESS");
// running the exe file immediately
if(!StartService(service_handle, 0, NULL))
printf("Start Service: FAILED | ERROR: %d\n", GetLastError());
else
puts("Service Start: SUCCESS");
CloseServiceHandle(SC_manager_handle);
CloseServiceHandle(service_handle);
return 0;
}

I think you miss some important requirements for a windows service.According to the MSDN.
You need a service main function and a control handler function as you can't handle the "start" command if there's no control handler function registered.
So you can refer to the code to know how to wrote a ServiceMain Function and install it.
If you want to open the service, according to Starting a Service:
To start a service, a service control program opens a handle to an
installed database and then specifies the handle in a call to the
StartService function. After starting the service, the program uses
the members of the SERVICE_STATUS_PROCESS structure returned by the
QueryServiceStatusEx function to track the progress of the service.
I recommend you refer to the complete sample of using the service, which will greatly help you use the service.
