3.26 Texture Reference Management 1633.26.1 Detailed DescriptionThis section describes the texture reference management functions of the low-level CUDA driver application programminginterface.3.26.2 Function Documentation3.26.2.1 CUresult cuTexRefCreate (CUtexref ∗ phTexRef)Creates a texture reference and returns its handle in ∗phTexRef. Once created, the application must call cuTexRefSetArray()or cuTexRefSetAddress() to associate the reference with allocated memory. Other texture reference functionsare used to specify the format and interpretation (addressing, filtering, etc.) to be used when the memory is readthrough this texture reference. To associate the texture reference with a texture ordinal for a given function, theapplication should call cuParamSetTexRef().Parameters:phTexRef - Returned texture referenceReturns:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUESee also:cuTexRefDestroy, cuTexRefSetAddress, cuTexRefSetAddress2D, cuTexRefSetAddressMode, cuTexRefSetArray,cuTexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress, cuTexRefGetAddressMode,cuTexRefGetArray, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormat3.26.2.2 CUresult cuTexRefDestroy (CUtexref hTexRef)Destroys the texture reference specified by hTexRef.Parameters:hTexRef - Texture reference to destroyReturns:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUESee also:cuTexRefCreate, cuTexRefSetAddress, cuTexRefSetAddress2D, cuTexRefSetAddressMode, cuTexRefSetArray,cuTexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress, cuTexRefGetAddress-Mode, cuTexRefGetArray, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormat3.26.2.3 CUresult cuTexRefGetAddress (CUdeviceptr ∗ pdptr, CUtexref hTexRef)Returns in ∗pdptr the base address bound to the texture reference hTexRef, or returns CUDA_ERROR_-INVALID_VALUE if the texture reference is not bound to any device memory range.Generated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
