Named events

CreateHookableEvent

Creates a hookable event.

Parameters
name
Type: string
Event name.
Result
Type: light userdata
Returns event descriptor if event was created successfully, else nil.
Example
local hEvent = m.CreateHookableEvent('MyEvent')

HookEvent

Sets a callback function ("trap") to react to event call. Traps are called one by one in the order they were added to the sequence.

Trap signature: function (wParam, lParam) return 0 end.

Correct result for a trap is 0. When 1 is returned, the following traps in a sequence won't be called.

Parameters
name
Type: string
Event name.
hook
Type: function
Trap function to be called when event occurs.
Result
Type: light userdata
Returns trap descriptor if trap was created successfully, else nil.
Example
local hHook = m.HookEvent('MyEvent', function(w, l)
  print('MyEvent is raised!')
end)

UnhookEvent

Removes "trap" from event call sequence.

Parameters
hEvent
Type: light userdata
Event descriptor received on CreateHookableEvent call.
Result
Type: boolean
Returns true if trap function was removed successfully, else false.
Example
m.UnhookEvent(hHook)

NotifyEventHooks

Calls all "traps" of event call sequence one by one.

Parameters
hEvent
Type: light userdata
Event descriptor received on CreateHookableEvent call.
wParam
lParam
Result
Type: boolean
Returns true if all trap functions were called, else false.
Example
m.NotifyEventHooks(hEvent)


Named service functions

CreateServiceFunction

Creates a service function ("service")

Parameters
name
Type: string
Service name.

local hService = m.CreateServiceFunction('MyService', function(w, l)
  print('MyServiceis called!')
end)

CallService

Calls service with parameters.

Parameters
name
Type: string
Service name.
wParam
lParam
Result
Type: number
Returns result of service execution or CALLSERVICE_NOTFOUND

ServiceExists

Checks if service exists by its name.

Parameters
name
Type: string
Service name.
Result
Type: boolean
Returns true if service exists, else false
Example

  m.CallService('MyService')
end

DestroyServiceFunction

Destroys a service function.

Parameters
