IDiskQuotaUser::SetQuotaLimit

Sets the user's quota limit value on the volume. The limit is set as the maximum amount of disk space available to the volume user.

HRESULT SetQuotaLimit(
  LONGLONG llLimit,
  BOOL fWriteThrough
);

llLimit: Specifies the limit value, in bytes. If this value is -1, the user has an unlimited quota.
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 once.
