Intel® Math Kernel Library 11.0.5 Reference Manual
This category contains the following functions: the value setting function DftiSetValue sets one particular configuration parameter to an appropriate value, and the value getting function DftiGetValue reads the value of one particular configuration parameter. While all configuration parameters are readable, you cannot set a few of them. Some of these contain fixed information of a particular implementation such as version number, or dynamic information, which is derived by the implementation during execution of one of the functions. See Configuration Settings for details.
