Binds size bytes of the memory area pointed to by devPtr to the texture reference texref. desc describes how the memory is interpreted when fetching values from the texture. Any memory previously bound to texref is unbound.
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 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 cudaMalloc(), the offset is guaranteed to be 0 and NULL may be passed as the offset parameter.
- Parameters:
-
| offset | - Offset in bytes |
| texref | - Texture to bind |
| devPtr | - Memory area on device |
| desc | - Channel format |
| size | - Size of the memory area pointed to by devPtr |
- Returns:
- cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidDevicePointer, cudaErrorInvalidTexture
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
