       Surface Reference Management -

   Functions
       cudaError_t cudaBindSurfaceToArray (const struct surfaceReference *surfref,
           cudaArray_const_t array, const struct cudaChannelFormatDesc *desc)
           Binds an array to a surface.
       cudaError_t cudaGetSurfaceReference (const struct surfaceReference **surfref, const void
           *symbol)
           Get the surface reference associated with a symbol.

Detailed Description

       \brief surface reference management functions of the CUDA runtime API (cuda_runtime_api.h)

       This section describes the low level surface reference management functions of the CUDA
       runtime application programming interface.

       Some functions have overloaded C++ API template versions documented separately in the C++
       API Routines module.

Function Documentation

   cudaError_t cudaBindSurfaceToArray (const struct surfaceReference * surfref, cudaArray_const_t
       array, const struct cudaChannelFormatDesc * desc)
       Binds the CUDA array array to the surface reference surfref. desc describes how the memory
       is interpreted when fetching values from the surface. Any CUDA array previously bound to
       surfref is unbound.

       Parameters:
           surfref - Surface to bind
           array - Memory array on device
           desc - Channel format

       Returns:
           cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidSurface

       Note:
           Note that this function may also return error codes from previous, asynchronous
           launches.

           descriptor), cudaGetSurfaceReference, cuSurfRefSetArray

   cudaError_t cudaGetSurfaceReference (const struct surfaceReference ** surfref, const void *
       symbol)
       Returns in *surfref the structure associated to the surface reference defined by symbol
       symbol.

       Parameters:
           surfref - Surface reference associated with symbol
           symbol - Surface to get reference for

       Returns:
           cudaSuccess, cudaErrorInvalidSurface

       Note:
           Note that this function may also return error codes from previous, asynchronous
           launches.

           Use of a string naming a variable as the symbol parameter was removed in CUDA 5.0.
