3.26 Texture Reference Management 167When using a tex2D() function inside a kernel, we have to either call cuTexRefSetArray() to bind the correspondingtexture reference to an array, or cuTexRefSetAddress2D() to bind the texture reference to linear memory.Function calls to cuTexRefSetFormat() cannot follow calls to cuTexRefSetAddress2D() for the same texture reference.Parameters:hTexRef - Texture reference to binddesc - Descriptor of CUDA arraydptr - Device pointer to bindPitchInBytes - Line pitch in bytesReturns:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUESee also:cuTexRefCreate, cuTexRefDestroy, cuTexRefSetAddress, cuTexRefSetAddressMode, cuTexRefSetArray, cu-TexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress, cuTexRefGetAddress-Mode, cuTexRefGetArray, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormat3.26.2.11 CUresult cuTexRefSetAddressMode (CUtexref hTexRef, int Dim, CUaddress_mode am)Specifies the addressing mode am for the given dimension Dim of the texture reference hTexRef. If Dim is zero,the addressing mode is applied to the first parameter of the functions used to fetch from the texture; if Dim is 1, thesecond, and so on. CUaddress_mode is defined as:typedef enum CUaddress_mode_enum {CU_TR_ADDRESS_MODE_WRAP = 0,CU_TR_ADDRESS_MODE_CLAMP = 1,CU_TR_ADDRESS_MODE_MIRROR = 2,} CUaddress_mode;Note that this call has no effect if hTexRef is bound to linear memory.Parameters:hTexRef - Texture referenceDim - Dimensionam - Addressing mode to setReturns:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUESee also:cuTexRefCreate, cuTexRefDestroy, cuTexRefSetAddress, cuTexRefSetAddress2D, cuTexRefSetArray, cu-TexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress, cuTexRefGetAddress-Mode, cuTexRefGetArray, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormatGenerated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
