application.QueueAsyncCall different in 32- or 64-bit?
« on: October 30, 2016, 04:42:43 pm »
Hi,
in laz 1.4.0 fpc 2.6.4 svn 48774, i386-win32- win32/win64, (windows 7 professional 32bit), I use this function :
application.QueueAsyncCall(@RunMyToko, FCT);     

on the other hand,
in laz 1.4.0 fpc 2.6.4 svn 48774, x86_64-win64-win32/win64 ,(windows 7 professional 64bit), it only compiles an runs like this:
application.QueueAsyncCall(RunMyToko, FCT);     

I don't understand why.  Any Idea?
grts,
guido

The @ is a fpc thing (at least by default) while not having to do so is more delphi like.

So a mode delphi switch (or not) could have triggered it), or a modeswitch.

Perhaps default behaviour was changed along the way (although i doubt it, it might be possible).

If not mistaken you can use modeswitch POINTERTOPROCVAR to change the behaviour.

You are right! It is the delphi switch that makes the difference.  Thank you for helping to clarify this.
