SetupDiBuildClassInfoListEx function

The SetupDiBuildClassInfoListEx function returns a list of setup class GUIDs that includes every class installed on the local system or a remote system.

Syntax


BOOL SetupDiBuildClassInfoListEx(
  _In_        DWORD Flags,
  _Out_opt_   LPGUID ClassGuidList,
  _In_        DWORD ClassGuidListSize,
  _Out_       PDWORD RequiredSize,
  _In_opt_    PCTSTR MachineName,
  _Reserved_  PVOID Reserved
);

Parameters

Flags [in]

Flags used to control exclusion of classes from the list. If no flags are specified, all setup classes are included in the list. Can be a combination of the following values:

DIBCI_NOINSTALLCLASS

Exclude a class if it has the NoInstallClass value entry in its registry key.

DIBCI_NODISPLAYCLASS

Exclude a class if it has the NoDisplayClass value entry in its registry key.

ClassGuidList [out, optional]

A pointer to a buffer that receives a list of setup class GUIDs.

ClassGuidListSize [in]

Supplies the number of GUIDs in the ClassGuildList array.

RequiredSize [out]

A pointer to a variable that receives the number of GUIDs returned. If this number is greater than the size of the ClassGuidList, the number indicates how large the ClassGuidList array must be in order to contain the list.

MachineName [in, optional]

A pointer to a NULL-terminated string that contains the name of a remote computer from which to retrieve installed setup classes. This parameter is optional and can be NULL. If MachineName is NULL, this function builds a list of classes installed on the local computer.
