I'm having trouble trying to get that to work..

DLLTest2.bmx
Strict
Framework brl.blitz

Function GetData( output:Int Var)
  output = 10
EndFunction


DllCaller2.bmx
Strict
Framework brl.blitz

Import pub.win32


Global data:Int = 0

Local Library = LoadLibraryA ( "DLLTest2.dll" )
If Not Library
  WriteStdout "Library not found!~n"
  Return
EndIf
Local GetData ( A ) = GetProcAddress ( Library , "GetData" )
If Not Getdata
  WriteStdout "GetData function not found!~n"
  Return
EndIf
GetData( data )
WriteStdout data
FreeLibrary Library

Extern "Win32"
  Function FreeLibrary ( Library )
EndExtern


DLLTest2.def
EXPORTS
GetData=bb_GetData



I get "Unhandled Memory Exception Error" when trying to call "GetData( data )".
