Constructor Detail

cudaPointerAttributes

public cudaPointerAttributes()

Default native constructor.

cudaPointerAttributes

public cudaPointerAttributes(long size)

Native array allocator. Access with Pointer.position(long).

cudaPointerAttributes

public cudaPointerAttributes(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

position

public cudaPointerAttributes position(long position)

Overrides:

position in class Pointer

memoryType

@Cast(value="cudaMemoryType")
public int memoryType()

The physical location of the memory, ::cudaMemoryTypeHost or ::cudaMemoryTypeDevice.

memoryType

public cudaPointerAttributes memoryType(int setter)

device

public int device()

The device against which the memory was allocated or registered. If the memory type is ::cudaMemoryTypeDevice then this identifies the device on which the memory referred physically resides. If the memory type is ::cudaMemoryTypeHost then this identifies the device which was current when the memory was allocated or registered (and if that device is deinitialized then this allocation will vanish with that device's state).

device

public cudaPointerAttributes device(int setter)

devicePointer

public Pointer devicePointer()

The address which may be dereferenced on the current device to access the memory or NULL if no such address exists.

devicePointer

public cudaPointerAttributes devicePointer(Pointer setter)

hostPointer

public Pointer hostPointer()

The address which may be dereferenced on the host to access the memory or NULL if no such address exists.

hostPointer

public cudaPointerAttributes hostPointer(Pointer setter)

isManaged

public int isManaged()

Indicates if this pointer points to managed memory

isManaged

public cudaPointerAttributes isManaged(int setter)
