Explicit kind parameter values are generally non-portable. I think that you can use a default INTEGER here.


acc_handle_kind = kind(0) or acc_handle_kind = selected_int_kind(9) would be better, I think.

Or define a PRIVATE parameter at the head of the file (integer, private, parameter :: default_int_kind(kind(0)) and use that. But kind(0) is idiomatic and clear.


Is your intent to implement these subprograms here in this module eventually?

If so, it might be better to define their module interfaces here in the module, and put their implementations into one or more submodules.

If not, then these subprograms should probably be just interfaces.

Address review comment

Thanks for the review comments. Just updated the patch.


Right, switch to INTEGER


I switched to use int32 from iso_fortran_env similar to what is done in gfortran.


They will most probably be implemented in other module/submodule so I made them interfaces.

@klausler Anything else to be changed?

If they're going to be implemented in a submodule (which makes sense to me), these interfaces should be module functions and subroutines. They can't be implemented in another module.
