IDiskQuotaControl::CreateEnumUsers

[This is preliminary documentation and subject to change.]

Creates an enumerator object for enumerating quota users on the volume. The newly created object implements the IEnumDiskQuotaUsers interface.

HRESULT CreateEnumUsers(
  PSID *rgpUserSids, 
  DWORD cpSids, 
  DWORD fNameResolution,
  PENUM_DISKQUOTA_USERS *ppEnum
);
 

Parameters

rgpUserSids

Array of security identifier (SID) pointers representing the user objects to be included in the enumeration. If this value is NULL, all user entries are enumerated.

cpSids

Number of items in the rgpUserSids array. Ignored if rgpUserSids is NULL.

fNameResolution

Indicates how the user account information is to be obtained. The volume's quota information identifies users by SID. The user account information (such as domain name, account name, and full name) must be obtained from the network domain controller, or the local computer if it is not on a network. This parameter can be one of the following values.

Value	Meaning
DISKQUOTA_USERNAME_RESOLVE_NONE	Do not resolve user account information.
DISKQUOTA_USERNAME_RESOLVE_SYNC	Resolve user account information synchronously. The IEnumDiskQuotaUsers::Next method returns when the information is resolved. If the information exists in the disk quota SID cache, it is returned immediately. Otherwise, the method must locate the information. This can take several seconds.
DISKQUOTA_USERNAME_RESOLVE_ASYNC	Resolve user account information asynchronously. The IEnumDiskQuotaUsers::Next method returns immediately. The caller must implement the IDiskQuotaEvents interface to receive notification when the information is available. If the information was cached during a previous request, notification occurs as soon as the object is serviced. Otherwise, the method obtains the information from the network domain controller, then notifies IDiskQuotaEvents.

ppEnum

Pointer to a pointer to the IEnumDiskQuotaUsers enumerator.

Return Values

This method returns one of the following values.
