       Surface Object Management -

   Functions
       CUresult cuSurfObjectCreate (CUsurfObject *pSurfObject, const CUDA_RESOURCE_DESC
           *pResDesc)
           Creates a surface object.
       CUresult cuSurfObjectDestroy (CUsurfObject surfObject)
           Destroys a surface object.
       CUresult cuSurfObjectGetResourceDesc (CUDA_RESOURCE_DESC *pResDesc, CUsurfObject
           surfObject)
           Returns a surface object's resource descriptor.

Detailed Description

       \brief surface object management functions of the low-level CUDA driver API (cuda.h)

       This section describes the surface object management functions of the low-level CUDA
       driver application programming interface. The surface object API is only supported on
       devices of compute capability 3.0 or higher.

Function Documentation

   CUresult cuSurfObjectCreate (CUsurfObject * pSurfObject, const CUDA_RESOURCE_DESC * pResDesc)
       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.

       Surface objects are only supported on devices of compute capability 3.0 or higher.
       Additionally, a surface object is an opaque value, and, as such, should only be accessed
       through CUDA API calls.

       Parameters:
           pSurfObject - Surface object to create
           pResDesc - Resource descriptor

       Returns:
           CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
           CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE

   CUresult cuSurfObjectDestroy (CUsurfObject surfObject)
       Destroys the surface object specified by surfObject.

       Parameters:
           surfObject - Surface object to destroy

       Returns:
           CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
           CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE

       See also:
           cuSurfObjectCreate, cudaDestroySurfaceObject

   CUresult cuSurfObjectGetResourceDesc (CUDA_RESOURCE_DESC * pResDesc, CUsurfObject surfObject)
       Returns the resource descriptor for the surface object specified by surfObject.

       Parameters:
           pResDesc - Resource descriptor
           surfObject - Surface object

       Returns:
           CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED,
           CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE
