dfti_handle_dst
| DFTI_DESCRIPTOR_HANDLE | The copy of the FFT descriptor. |
status
| MKL_LONG | Function completion status. |
Description
This function makes a copy of an existing descriptor. The resulting descriptor
desc_handle_copy
and the existing descriptor desc_handle_original
specify the same configuration of the transform, but do not have any memory areas in common ("deep copy").The function returns zero when it completes successfully.
See Status Checking Functions for more information on the returned status.
