The FeatureGetCost function is obsolete. Use the FeatureGetCostEx function instead.
The FeatureGetCost function determines the total space, in kilobytes (KB), required on the target drive for the feature that is specified by szFeature. When determining required drive space, this function takes into account whether the feature is currently selected, whether any components associated with the feature are currently filtered by operating system or language, and the cluster size on the target drive.
Syntax
FeatureGetCost ( szFeatureSource, szFeature, szTargetDir, nvRequiredSpace );
Parameters
|

|
szTargetDir |
Specifies the drive that is used, or the path whose drive is used, in determining required drive space. Typically, you would pass the system variable TARGETDIR in this parameter. |
