CopyDescriptor

Syntax

Fortran:

Status = DftiCopyDescriptor( Desc_Handle_Original, Desc_Handle_Copy )

C:

status = DftiCopyDescriptor( desc_handle_original, &desc_handle_copy );

Include Files

The Fortran interface is specified in the mkl_dfti.f90 include file and the C interface is specified in the mkl_dfti.h include file.

Description

This function makes a copy of an existing descriptor and provides a pointer to it. The purpose is that all information of the original descriptor will be maintained even if the original is destroyed via the free descriptor function DftiFreeDescriptor.

The function returns the zero status when completes successfully. The function returns DFTI_NO_ERROR when completes successfully. See Status Checking Functions for more information on the returned status.
