Thanks for the fixes to my C library Tomasz and for your help.

All my C Library is originally extracted from FreeUDFLibC and I added extra functions.

There were errors in the C Code that I was unaware of.

Amazing that the same unaltered code works under CenTos 64 bit in 2.1 though.

Still do not understand why my freepascal UDF is crashing.

I think we will stick to using "C" now.

Even though it is a TERRIBLE language!

Kind Regards,

Robert.
