<div><p style="margin-top:0px" dir="ltr">Yes that would work, but then I have to figure out the address width myself at compile time.</p>
<p dir="ltr"> I would need to compile for each architecture . </p>
<p dir="ltr"> 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 ... </p>
<p dir="ltr">Pointers are basically unsigned values which match size_t's nominal type and length.</p>
<p dir="ltr">The cint and clong function are signed so it does take a little bit if fiddling to work properly.</p>
<p dir="ltr">More testing needed of course.</p>
