I don't know if we used VMS C from Dec. I
have a feeling if you ran
Eunice, you used pcc or a derivative of pcc. Cross library calling was
pretty straightforward (ok, so passing function addresses and dynamic
structures into FORTRAN not such) [...]
Hhmmm... I recall using DEC's C compiler, which we called VAX C.
Calling C stuff from VAX FORTRAN required jiggery-pokery and the other
way was hopeless. I recall (assuming no wetware bit-rot on my part)
that DEC's languages did not pass on the stack but stuffed the
arguments somewhere, passing a pointer to the somewhere.
