[Gambas-user] Moving from 64bit to 32 bit and back

[Brian G]

Yes that would work, but then I have to figure out the address width myself at compile time.
   I would need to compile for each architecture . 
  I was trying to find a way to make the code portable that requires no recompile for SAME OS 32 AND 64 BIT VERSION. The same package can be installed on both versions and call c functions and pass structures without any issues....... So far lol  ... with such in-depth testing I have done... Three or four times ... 
Pointers are basically unsigned values which match size_t's nominal type and length.
The cint and clong function are signed so it does take a little bit if fiddling to work properly.
More testing needed of course.
