Syntax

public static class SurfaceReferenceManagement

Methods

cuSurfRefGetArray(ref CUarray, CUsurfref)

Returns in phArray the CUDA array bound to the surface reference hSurfRef, or returns ErrorInvalidValue if the surface reference is not bound to any CUDA array.

Declaration

public static CUResult cuSurfRefGetArray(ref CUarray phArray, CUsurfref hSurfRef)

Parameters

Type	Name	Description
CUarray	phArray	Surface reference handle
CUsurfref	hSurfRef	Surface reference handle

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue. Note that this function may also return error codes from previous, asynchronous launches.

cuSurfRefSetArray(CUsurfref, CUarray, CUSurfRefSetFlags)

Sets the CUDA array hArray to be read and written by the surface reference hSurfRef. Any previous CUDA array state associated with the surface reference is superseded by this function. Flags must be set to None. The SurfaceLDST flag must have been set for the CUDA array. Any CUDA array previously bound to hSurfRef is unbound.

Declaration

public static CUResult cuSurfRefSetArray(CUsurfref hSurfRef, CUarray hArray, CUSurfRefSetFlags Flags)

Parameters

Type	Name	Description
CUsurfref	hSurfRef	Surface reference handle
CUarray	hArray	CUDA array handle
CUSurfRefSetFlags	Flags	set to None

Returns

Type	Description
CUResult	CUDA Error Codes: Success, ErrorDeinitialized, ErrorNotInitialized, ErrorInvalidContext, ErrorInvalidValue. Note that this function may also return error codes from previous, asynchronous launches.
