Source 
pub unsafe extern "C" fn get_cuda_pci_address_from_ptr(
    cuda_ptr: CUdeviceptr,
    pci_addr_out: *mut c_char,
    pci_addr_size: usize,
) -> c_int
Expand description

Get PCI address from a CUDA/HIP device pointer

In CUDA builds, cuda_ptr is CUdeviceptr (u64). In ROCm builds, cuda_ptr is CUdeviceptr (aliased to hipDeviceptr_t = void*).
