Package svc provides everything required to build Windows service.

func IsAnIinteractiveSession

func IsAnIinteractiveSession() (bool, error)

IsAnIinteractiveSession is a misspelled version of IsAnInteractiveSession. Do not use. It is kept here so we do not break existing code.

func IsAnInteractiveSession

func IsAnInteractiveSession() (bool, error)

IsAnInteractiveSession determines if calling process is running interactively. It queries the process token for membership in the Interactive group.

func Run

func Run(name string, handler Handler) error

Run executes service named name by calling appropriate handler function.


type Accepted

type Accepted uint32

Accepted is used to describe commands accepted by the service. Note, that Interrogate is always accepted.

type ChangeRequest

type ChangeRequest struct {
	Cmd           Cmd
	CurrentStatus Status

ChangeRequest is sent to service Handler to request service status change.

type Cmd

type Cmd uint32

Cmd represents service state change request. It is sent to a service by the service manager, and should be actioned upon by the service.

type Handler

type Handler interface {

	// Execute will be called by the package code at the start of
	// the service, and the service will exit once Execute completes.
	// Inside Execute you must read service change requests from r and
	// act accordingly. You must keep service control manager up to date
	// about state of your service by writing into s as required.
	// args contains argument strings passed to the service.
	// You can provide service exit code in exitCode return parameter,
	// with 0 being "no error". You can also indicate if exit code,
	// if any, is service specific or not by using svcSpecificEC
	// parameter.
	Execute(args []string, r <-chan ChangeRequest, s chan<- Status) (svcSpecificEC bool, exitCode uint32)

Handler is the interface that must be implemented to build Windows service.

type State

type State uint32

State describes service execution state (Stopped, Running and so on).

type Status

type Status struct {
	State      State
	Accepts    Accepted
	CheckPoint uint32 // used to report progress during a lengthy operation
	WaitHint   uint32 // estimated time required for a pending operation, in milliseconds

Status combines State and Accepted commands to fully describe running service.



  • There is no mechanism to run multiple services inside one single executable. Perhaps, it can be overcome by using RegisterServiceCtrlHandlerEx Windows api.
