Methods

cuSurfObjectCreate(ref CUsurfObject, ref CudaResourceDesc)

Creates a surface object and returns it in pSurfObject. pResDesc describes the data to perform surface load/stores on. ::CUDA_RESOURCE_DESC::resType must be ::CU_RESOURCE_TYPE_ARRAY and ::CUDA_RESOURCE_DESC::res::array::hArray must be set to a valid CUDA array handle. ::CUDA_RESOURCE_DESC::flags must be set to zero.

Declaration

public static CUResult cuSurfObjectCreate(ref CUsurfObject pSurfObject, ref CudaResourceDesc pResDesc)

Parameters

Type	Name	Description
CUsurfObject	pSurfObject	Surface object to create
CudaResourceDesc	pResDesc	Resource descriptor

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue.

cuSurfObjectDestroy(CUsurfObject)

Destroys the surface object specified by surfObject.

Declaration

public static CUResult cuSurfObjectDestroy(CUsurfObject surfObject)

Parameters

Type	Name	Description
CUsurfObject	surfObject	Surface object to destroy

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue.

cuSurfObjectGetResourceDesc(ref CudaResourceDesc, CUsurfObject)

Returns the resource descriptor for the surface object specified by surfObject.

Declaration

public static CUResult cuSurfObjectGetResourceDesc(ref CudaResourceDesc pResDesc, CUsurfObject surfObject)

Parameters

Type	Name	Description
CudaResourceDesc	pResDesc	Resource descriptor
CUsurfObject	surfObject	Surface object

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue.
