C interoperability with assumed-shape arrays

[rwmsu]

My biggest problem with ISO_Fortran_binding.h and assumed shape arrays is that it forces me to write more C code than I need. To me that defeats the purpose of the original idea behind the Fortran C-Interop facility. Basically, if you know the C function prototype you can call a C function without writing any additional C code. Conversely, on the C side all you have to do is write a conforming function prototype for the Fortran routine and call it without resorting to convoluted name mangling. However, I’ll admit that 99.99% of my forays into C-Interop has been Fortran calling C so I rarely see a need for writing another C wrapper around my target C routine just so I can use assumed shape arrays.
