Note • This function is obsolete. Use the FeatureGetCostEx function instead.
Project • This information applies to the following project types:

The FeatureGetTotalCost function determines the total space, in kilobytes (KB), required on the target drive for the feature installations and uninstallations that have been specified (for example, by end user selections in feature or setup type dialogs). When determining required drive space, this function takes into account which features are currently selected, whether any components associated with the features are currently filtered by operating system or language, and the cluster size on the target drive.
