// Pure constructor: every call allocates a brand-new ANSAWSS3 and writes it to
// *Handle. *Handle(in) is ignored completely -- LabVIEW's CLF Node marshalling
// reuses the same temp buffer per call site, so *Handle(in) often contains
// leftover bytes from the previous Create's output even when the actual LabVIEW
// wire is a different, freshly-allocated instance. Inspecting *Handle(in) for
// "is this live?" detection cannot distinguish that case from a genuine
// double-Create-on-same-wire, so we don't try -- we trust the caller.
//
// Trade-off: if a caller really does call Create twice on the same wire without
// Release, the first handle leaks. That is the caller's bug. The alternative
// (releasing live objects we "see" in the input) destroys legitimate parallel
// instances and is far worse.
//
// Return codes:
//   1  : success, *Handle now points to a new registered instance
//   0  : invalid arg, alloc failure, or Initialize() failed
