C++ calling Ada code?

C++ calling Ada code?

[Caroline]

We will be working on a project where we will use C++ code (written by
us) to talk to and use Ada code (not written by us).  Are there
resources available that you know of on how to get C++ to call Ada
routines?  Has anyone tried this?

Thanks
Caroline

The simplest way of doing this if you just want to call Ada
subprograms from C++ is probably to export your Ada programs with
convention C (see the reference manual) and declare those functions in
C++ with "extern C".

You may need to call "adainit" and "adafinal" too, to ensure that the
all the necessary Ada code gets elaborated.
