Use uintptr_t

uintptr_t is part of the C standard (<stdint.h>), so it works on all major platforms, including Linux, macOS, and Windows, for both 32-bit and 64-bit architectures.

On 32-bit systems, uintptr_t is a 32-bit unsigned integer.
On 64-bit systems, uintptr_t is a 64-bit unsigned integer.

It’s specifically designed for storing pointer values as integers safely, so any pointer-to-integer or integer-to-pointer cast using uintptr_t is portable and safe, unlike using unsigned int, which can break on 64-bit systems.
