This is provided by "Runtime Packages" with Delphi.
Michael, it seems that you understood Lukasz wrong, this has nothing to
do with runtime packages. He has a Pascal/Lazarus application and has a
C(++) library where he wants to provide a unit for. Now this library has
a callback (for the application) which is called in a different thread.
In this context it would be perfectly legal to use e.g.
Application.QueueAsyncCall, but he wants to keep his interface unit
independant of Lazarus. Thus in this situation he should - as Henry
wrote - provide an event that is called by the callback and which can
then be set by the calling application.
Regards,
Sven
