Prototype

BOOL WINAPI StartService(
  SC_HANDLE hService,
  DWORD dwNumServiceArgs,
  LPCTSTR* lpServiceArgVectors
);

Parameters

hService

[in] Handle to the service. This handle is returned by the OpenService or CreateService function, and it must have the SERVICE_START access right. For more information, see Service Security and Access Rights.

dwNumServiceArgs

[in] Number of strings in the lpServiceArgVectors array. If lpServiceArgVectors is NULL, this parameter can be zero.

lpServiceArgVectors

[in] Pointer to an array of pointers to null-terminated strings to be passed to a service as arguments. Driver services do not receive these arguments. If no arguments are passed to the service, this parameter can be NULL. The service accesses these arguments through its ServiceMain function. The first argument (argv[0]) is the name of the service by default, followed by the arguments, if any, in the lpServiceArgVectors array.

Return Value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

The following error codes can be set by the service control manager. Others can be set by the registry functions that are called by the service control manager.

ERROR_SERVICE_NO_THREAD
