Input Parameters

Name	Type	Description
`desc_handle`	`DFTI_DESCRIPTOR`	FFT descriptor.
`config_param`	`INTEGER`	Configuration parameter. See the Configuration Parameters tables for allowable values of `config_param`.

Output Parameters

Name	Type	Description
`config_val`	Depends on the configuration parameter.	Configuration value.
`status`	`INTEGER`	Function completion status.

Description

This function gets the configuration value of one particular configuration parameter. Each configuration parameter is a named constant, and the configuration value must have the corresponding type, which can be a named constant or a native type. For available configuration parameters and the corresponding configuration values, see:

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