6.27. Surface Reference Management [DEPRECATED]
This section describes the surface reference management functions of the low-level CUDA driver application programming interface.
Functions
- CUresult cuSurfRefGetArray ( CUarray* phArray, CUsurfref hSurfRef )
- Passes back the CUDA array bound to a surface reference.
- CUresult cuSurfRefSetArray ( CUsurfref hSurfRef, CUarray hArray, unsigned int Flags )
- Sets the CUDA array for a surface reference.
Functions
- CUresult cuSurfRefGetArray ( CUarray* phArray, CUsurfref hSurfRef )
-
Passes back the CUDA array bound to a surface reference.
Parameters
- phArray
- - Surface reference handle
- hSurfRef
- - Surface reference handle
Returns
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE
Deprecated
Description
Returns in *phArray the CUDA array bound to the surface reference hSurfRef, or returns CUDA_ERROR_INVALID_VALUE if the surface reference is not bound to any CUDA array.See also:
- CUresult cuSurfRefSetArray ( CUsurfref hSurfRef, CUarray hArray, unsigned int Flags )
-
Sets the CUDA array for a surface reference.
Parameters
- hSurfRef
- - Surface reference handle
- hArray
- - CUDA array handle
- Flags
- - set to 0
Returns
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE
Deprecated
Description
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 Any previous CUDA array state associated with the surface reference is superseded by this function.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 0. The CUDA_ARRAY3D_SURFACE_LDST flag must have been set for the CUDA array. Any CUDA array previously bound to hSurfRef is unbound.See also:
