Issue #5992 has been reported by Nobuyoshi Nakada.

----------------------------------------
Feature #5992: DL and fiddle should support intrinsic types, size_t, ptrdiff_t and intptr_t
https://bugs.ruby-lang.org/issues/5992

Author: Nobuyoshi Nakada
Status: Open
Priority: Normal

Category: ext
Target version: 2.0.0


size_t and ptrdiff_t can be resulted by built-in operators, so they should be provided as well as other primitive types.

Also ruby often needs uintptr_t as VALUE.

Patch attached.
