Hello:
I want to pass structures between F95 and C and one way I thought of
doing it was to create a structure that had the same layout in memory on
both the Fortran side and the C side.
I did a little testing and I see that this works but my question is can
I count on different compilers on the *same* platform laying out the
same structure in the same way in memory? (I know I cannot count on the
memory layout to be the same on different platforms). For example, if I
had the structure:
type this_type
real abc
type (sub_type) xyz
... etc.
end type
Will on linux, say, the NAG and Lahey compilers create the same memory
layout for this structure?
-- Thanks for any help, David Sagan
