   Tentatively assign to myself to complete the design.

    Hi @kimud6003, sorry that your question fell through the cracks. The cuIpcGetMemHandle API from the driver module takes only 1 argument: https://nvidia.github.io/cuda-python/cuda-bindings/latest/module/driver.html#cuda.bindings.driver.cuIpcGetMemHandle
    I believe the confusion comes from the fact that we perform aggressive argument transform in cuda.bindings, so unlike the raw C APIs the output-only args are returned directly as part of the return value.

    This issue is not about cuda.bindings, though. It's about pythonic exposure of IPC support in cuda.core, and very soon we'll enable it for Linux users 🙂
