Hello Cesar,

"What about those Marshaling functions that you provide ?
How fast are they ?"

They are quite fast, especially the marshaling functions that convert VFP arrays/cursors to C arrays are several hundred times faster than anything one could write with VFP code.

But how does this relate to this topic?

These functions were designed to emulate C structures easily (semi automatic conversion is done by the provided struct translator application) from VFP without thinking about datatype conversion, structure alignment etc. .

VFP is just the wrong tool for any algorithm that has to deal with data on a per byte basis.
