CUresult cuTexRefSetAddress (size_t * ByteOffset, CUtexref hTexRef, CUdeviceptr dptr, size_t bytes)

Deprecated
Binds a linear address range to the texture reference hTexRef. Any previous address or CUDA array state associated with the texture reference is superseded by this function. Any memory previously bound to hTexRef is unbound.
Since the hardware enforces an alignment requirement on texture base addresses, cuTexRefSetAddress() passes back a byte offset in *ByteOffset that must be applied to texture fetches in order to read from the desired memory. This offset must be divided by the texel size and passed to kernels that read from the texture so they can be applied to the tex1Dfetch() function.
If the device memory pointer was returned from cuMemAlloc(), the offset is guaranteed to be 0 and NULL may be passed as the ByteOffset parameter.
The total number of elements (or texels) in the linear address range cannot exceed CU_DEVICE_ATTRIBUTE_MAXIMUM_TEXTURE1D_LINEAR_WIDTH. The number of elements is computed as (bytes / bytesPerElement), where bytesPerElement is determined from the data format and number of components set using cuTexRefSetFormat().
Parameters:
ByteOffset - Returned byte offset
hTexRef - Texture reference to bind
dptr - Device pointer to bind
bytes - Size of memory to bind in bytes
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE
See also:
cuTexRefSetAddress2D, cuTexRefSetAddressMode, cuTexRefSetArray, cuTexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress, cuTexRefGetAddressMode, cuTexRefGetArray, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormat, cudaBindTexture

CUresult cuTexRefSetAddress2D (CUtexref hTexRef, const CUDA_ARRAY_DESCRIPTOR * desc, CUdeviceptr dptr, size_t Pitch)

Deprecated
Binds a linear address range to the texture reference hTexRef. Any previous address or CUDA array state associated with the texture reference is superseded by this function. Any memory previously bound to hTexRef is unbound.
Using a tex2D() function inside a kernel requires a call to either cuTexRefSetArray() to bind the corresponding texture 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.
It is required that dptr be aligned to the appropriate hardware-specific texture alignment. You can query this value using the device attribute CU_DEVICE_ATTRIBUTE_TEXTURE_ALIGNMENT. If an unaligned dptr is supplied, CUDA_ERROR_INVALID_VALUE is returned.
Pitch has to be aligned to the hardware-specific texture pitch alignment. This value can be queried using the device attribute CU_DEVICE_ATTRIBUTE_TEXTURE_PITCH_ALIGNMENT. If an unaligned Pitch is supplied, CUDA_ERROR_INVALID_VALUE is returned.
Width and Height, which are specified in elements (or texels), cannot exceed CU_DEVICE_ATTRIBUTE_MAXIMUM_TEXTURE2D_LINEAR_WIDTH and CU_DEVICE_ATTRIBUTE_MAXIMUM_TEXTURE2D_LINEAR_HEIGHT respectively. Pitch, which is specified in bytes, cannot exceed CU_DEVICE_ATTRIBUTE_MAXIMUM_TEXTURE2D_LINEAR_PITCH.
Parameters:
hTexRef - Texture reference to bind
desc - Descriptor of CUDA array
dptr - Device pointer to bind
Pitch - Line pitch in bytes
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE
See also:
cuTexRefSetAddress, cuTexRefSetAddressMode, cuTexRefSetArray, cuTexRefSetFilterMode, cuTexRefSetFlags, cuTexRefSetFormat, cuTexRefGetAddress, cuTexRefGetAddressMode, cuTexRefGetArray, cuTexRefGetFilterMode, cuTexRefGetFlags, cuTexRefGetFormat, cudaBindTexture2D

CUresult cuTexRefSetAddressMode (CUtexref hTexRef, int dim, CUaddress_mode am)

Deprecated
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, the second, 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,
      CU_TR_ADDRESS_MODE_BORDER = 3
   } CUaddress_mode;

Note that this call has no effect if hTexRef is bound to linear memory. Also, if the flag, CU_TRSF_NORMALIZED_COORDINATES, is not set, the only supported address mode is CU_TR_ADDRESS_MODE_CLAMP.
Parameters:
hTexRef - Texture reference
dim - Dimension
am - Addressing mode to set
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE

CUresult cuTexRefSetArray (CUtexref hTexRef, CUarray hArray, unsigned int Flags)

Deprecated
Binds the CUDA array hArray to the texture reference hTexRef. Any previous address or CUDA array state associated with the texture reference is superseded by this function. Flags must be set to CU_TRSA_OVERRIDE_FORMAT. Any CUDA array previously bound to hTexRef is unbound.
Parameters:
hTexRef - Texture reference to bind
hArray - Array to bind
Flags - Options (must be CU_TRSA_OVERRIDE_FORMAT)
Returns:
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE

The color value supports only float type and holds color components in the following sequence: pBorderColor[0] holds ’R’ component pBorderColor[1] holds ’G’ component pBorderColor[2] holds ’B’ component pBorderColor[3] holds ’A’ component
Note that the color values can be set only when the Address mode is set to CU_TR_ADDRESS_MODE_BORDER using cuTexRefSetAddressMode. Applications using integer border color values have to ’reinterpret_cast’ their values to float.

Deprecated
Specifies the filtering mode fm to be used when reading memory through the texture reference hTexRef. CUfilter_mode_enum is defined as:
   typedef enum CUfilter_mode_enum {
      CU_TR_FILTER_MODE_POINT = 0,

CUresult cuTexRefSetFlags (CUtexref hTexRef, unsigned int Flags)

Deprecated
Specifies optional flags via Flags to specify the behavior of data returned through the texture reference hTexRef. The valid flags are:
o CU_TRSF_READ_AS_INTEGER, which suppresses the default behavior of having the texture promote integer data to floating point data in the range [0, 1]. Note that texture with 32-bit integer format would not be promoted, regardless of whether or not this flag is specified;
o CU_TRSF_NORMALIZED_COORDINATES, which suppresses the default behavior of having the texture coordinates range from [0, Dim) where Dim is the width or height of the CUDA array. Instead, the texture coordinates [0, 1.0) reference the entire breadth of the array dimension;
Parameters:
hTexRef - Texture reference
