I'm porting a large mixed language product to run under NT. Some source files are in Fortran, some in C. I've managed to generate Fortran prototypes for most of the C functions, but I don't know how to deal with 'void*' arguments as in:
void func (void * foo);
Of course, the intent is to be able to provide the function with any type of argument by reference without compiler complaint.
My latest thoughts are to somehow use a Fortran pointer when calling such a C function, but I'm not sure which pointer type to use, or how to best arrange things. Any advice out there?
