Yes. Thanks for the link. Note 15.18 makes sense, there's really
nothing else that would work. I'm more concerned with
Note 15.16, which reads
"An element of a multi-dimensional C array is an array type,
so a Fortran array of rank one is not interoperable with a
multidimensional C array."
I'm note sure what this means. My understanding of the C standard
for data layout is that a multi-dimensional C array is stored
continuously in the obvious fashion. In other words, a multi-dimensional
C array is completely interoperable with a rank-one C array. So why
wouldn't it be interoperable with a rank-one fortran array? They're
both just the obvious continuous list of data. Anyway, this is
not a central issue; I'm just wondering what I am missing with
that statement.
