Struct cudaPointerAttributes 

#[repr(C)]
pub struct cudaPointerAttributes {
    pub type_: c_int,
    pub device: c_int,
    pub device_pointer: *mut c_void,
    pub host_pointer: *mut c_void,
}

cudaPointerAttributes — returned by cudaPointerGetAttributes.

The C struct is 48 bytes. We model the fields directly.

Fields

type_: c_int

cudaMemoryType — 0=unregistered, 1=host, 2=device, 3=managed.

device: c_int

Device ordinal the allocation lives on.

device_pointer: *mut c_void

Device-addressable pointer (null for plain host memory).

host_pointer: *mut c_void

Host-addressable pointer (null for plain device memory).
