Re: Question about _Rreadn C function

["Charles Wilt" <charles.wilt@xxxxxxxxx>]

Thanks Elvis,

Looks like it is also in _RFILE.buf_length.

I'll use that one, otherwise I have to figure out how to get/use the
feedback info. <grin>

I've got those two manuals open, but IMHO they are not organized real
well.  In fact, I did find a description of _RFILE and _RIOFB_T.  But
the description only cover a few of the subfields not all of them.  In
particular, _RFILE.buf_len is not mentioned.

Thanks again,
Charles
