Examples

dllpath:=A_AhkDir "\AutoHotkey.dll"
DllCall("LoadLibrary","Str",dllpath) ; Load the AutoHotkey module.
DllCall(dllpath "\ahktextdll","Str","#Persistent`nMyFunc(param){`nSleep 10000`nMsgBox `% param`n}","Str","","CDecl") ; start a new thread, just the function.
Msgbox % DllCall(dllpath "\ahkFunction","Str","MyFunc","Str","Hello World!","CDecl Str") ; call the function.

; Same example like above using internal AutoHotkey.dll
dll:=AhkThread("#Persistent`nMyFunc(param){`nSleep 10000`nMsgBox `% param`n}")
MsgBox % dll.ahkFunction["MyFunc","test"]
