Input Parameters

Name

Type

Description

desc_handle

DFTI_DESCRIPTOR

FFT descriptor.

config_param

INTEGER

Configuration parameter. See Table "Configuration Parameters" 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.
