NVCVStatus nvcvTensorWrapDataConstruct(const NVCVTensorData *data, NVCVTensorDataCleanupFunc cleanup, void *ctxCleanup, NVCVTensorHandle *handle)

Wraps an existing tensor buffer into an NVCV tensor instance constructed in given storage

It allows for interoperation of external tensor representations with NVCV.

Parameters:

• data – [in] Tensor contents.

  • Must not be NULL.

  • Allowed buffer types:

    • NVCV_TENSOR_BUFFER_STRIDED_CUDA

• cleanup – [in] Cleanup function to be called when the tensor is destroyed via nvcvTensorDecRef. If NULL, no cleanup function is defined.

• ctxCleanup – [in] Pointer to be passed unchanged to the cleanup function, if defined.

• handle – [out] Where the tensor instance handle will be written to.

  • Must not be NULL.

Return values:

• NVCV_ERROR_INVALID_ARGUMENT – Some parameter is outside valid range.

• NVCV_ERROR_OUT_OF_MEMORY – Not enough memory to create the tensor.

• NVCV_SUCCESS – Operation executed successfully.
