Request - provide a C function pointer type

[vimirage]

Problems Description

Upstream issues: denoland/deno#15292(, tov/libffi-rs#57).

The only reference to using pointers in function signatures that I found was as follows:

ffi_type_pointer
A generic void * pointer. You should use this for all
pointers, regardless of their real type.

The problem with this is that as void * is a data pointer, it is not suitable for usage as a function pointer.
See https://c-faq.com/ptrs/generic.html.

The request is that a separate ffi_function_pointer is provided, mapping to C's void(*)().

Fair point. What platforms is this a real problem on?

[vimirage]

We have not encountered any platform yet that actually incur such breakage/mismatch - at the moment, it's primarily a "technically this should be avoided" by the specification, situation.

If the lack of "realism" is not a deal-breaker, would the project be open to any commits adding such a feature?

[atgreen]

Yes, a patch would be welcome. AG
