Any memory previously bound to texref isunbound.Since the hardware enforces an alignment requirement on texture base addresses, cudaBindTexture() returns in∗offset a byte offset that must be applied to texture fetches in order to read from the desired memory. This offsetmust be divided by the texel size and passed to kernels that read from the texture so they can be applied to theGenerated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
