IDiskQuotaUser::SetQuotaThreshold method (dskquota.h)

  • Article

Sets the user's warning threshold value on the volume. The threshold is an arbitrary value set by the volume's quota administrator. You can use it to identify users who are approaching their hard quota limit.

Syntax

HRESULT SetQuotaThreshold(
  [in] LONGLONG llThreshold,
  [in] BOOL     fWriteThrough
);

Parameters

[in] llThreshold

The warning threshold value, in bytes.

[in] fWriteThrough

If this value is TRUE, the value is written immediately to the volume's quota file. Otherwise, the value is written only to the quota user object's local memory. This value should typically be set to TRUE. Set it to FALSE when using the IDiskQuotaUserBatch interface to modify multiple user quota entries at the same time.

Return value

This method returns a file system error or one of the following values.
