Overview of the Group Policy API technology.
To develop Group Policy API, you need these headers:

| ImportRSoPData The ImportRSoPData function imports a data file containing RSoP data to a WMI namespace. The file must be one generated by a call to the ExportRSoPData function. |
| InstallApplication The InstallApplication function can install applications that have been deployed to target users that belong to a domain. |
| LeaveCriticalPolicySection The LeaveCriticalPolicySection function resumes the background application of policy. This function closes the handle to the policy section. |

| IRSOPInformation The IRSOPInformation interface provides methods for Microsoft Management Console (MMC) extension snap-ins to communicate with the main Resultant Set of Policy (RSoP) snap-in. For more information about MMC, see the Microsoft Management Console. |
Structures
| GPOBROWSEINFO The GPOBROWSEINFO structure contains information that the BrowseForGPO function uses to initialize a GPO browser dialog box. After the user closes the dialog box, the system returns information about the user's actions in this structure. |
