186 Module Documentation 4.31.1 Detailed Description This section describes the texture reference management functions of the low-level CUDA driver application programming interface. 4.31.2 Function Documentation 4.31.2.1 cuTexRefCreate (CUtexref ∗ pTexRef) Creates a texture reference and returns its handle in ∗pTexRef. Once created, the application must call cuTexRefSetArray() or cuTexRefSetAddress() to associate the reference with allocated memory. Other texture reference functions are used to specify the format and interpretation (addressing, filtering, etc.) to be used when the memory is read through this texture reference. To associate the texture reference with a texture ordinal for a given function, the application should call cuParamSetTexRef(). Parameters: pTexRef - Returned texture reference Returns: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_- ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE See also: cuTexRefDestroy, cuTexRefSetAddress, cuTexRefSetAddress2D, cuTexRefSetAddressMode, cuTexRefSetArray, cuTexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress, cuTexRefGetAddressMode, cuTexRefGetArray, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormat 4.31.2.2 cuTexRefDestroy (CUtexref hTexRef) Destroys the texture reference specified by hTexRef. Parameters: hTexRef - Texture reference to destroy Returns: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_- ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE See also: cuTexRefCreate, cuTexRefSetAddress, cuTexRefSetAddress2D, cuTexRefSetAddressMode, cuTexRefSetArray, cuTexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress, cuTexRefGetAddress- Mode, cuTexRefGetArray, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormat 4.31.2.3 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 for NVIDIA CUDA Library by Doxygen
4.31 Texture Reference Management 187 Parameters: pdptr - Returned device address hTexRef - Texture reference Returns: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_- ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE See also: cuTexRefCreate, cuTexRefDestroy, cuTexRefSetAddress, cuTexRefSetAddress2D, cuTexRefSetAddressMode, cuTexRefSetArray, cuTexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress- Mode, cuTexRefGetArray, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormat 4.31.2.4 cuTexRefGetAddressMode (CUaddress_mode ∗ pam, CUtexref hTexRef, int dim) Returns in ∗pam the addressing mode corresponding to the dimension dim of the texture reference hTexRef. Currently, the only valid value for dim are 0 and 1. Parameters: pam - Returned addressing mode hTexRef - Texture reference dim - Dimension Returns: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_- ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE See also: cuTexRefCreate, cuTexRefDestroy, cuTexRefSetAddress, cuTexRefSetAddress2D, cuTexRefSetAddressMode, cuTexRefSetArray, cuTexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress, cu- TexRefGetArray, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormat 4.31.2.5 cuTexRefGetArray (CUarray ∗ phArray, CUtexref hTexRef) Returns in ∗phArray the CUDA array bound to the texture reference hTexRef, or returns CUDA_ERROR_- INVALID_VALUE if the texture reference is not bound to any CUDA array. Parameters: phArray - Returned array hTexRef - Texture reference Returns: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_- ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE See also: cuTexRefCreate, cuTexRefDestroy, cuTexRefSetAddress, cuTexRefSetAddress2D, cuTexRefSetAddressMode, cuTexRefSetArray, cuTexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress, cu- TexRefGetAddressMode, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormat Generated for NVIDIA CUDA Library by Doxygen
