VaultGetSize Event

Fires to determine the size of a callback mode vault.


class CBDriveVaultGetSizeEventParams {
  qint64 VaultHandle();
  qint64 Size();
  void SetSize(qint64 lSize);
  int ResultCode();
  void SetResultCode(int iResultCode);
  int EventRetVal();
  void SetEventRetVal(int iRetVal);
// To handle, connect one or more slots to this signal. void VaultGetSize(CBDriveVaultGetSizeEventParams *e);
// Or, subclass CBDrive and override this emitter function. virtual int FireVaultGetSize(CBDriveVaultGetSizeEventParams *e) {...}


This event fires when the class needs to determine the size of the callback mode vault specified by VaultHandle.

This event only needs to be handled if the CallbackMode property is enabled; please refer to the Callback Mode topic for more information. To handle this event properly, applications must set Size to indicate the size, in bytes, of the vault specified by VaultHandle.

The VaultHandle parameter contains an application-defined handle to an open callback mode vault, as returned by the application in an earlier VaultOpen event.

The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
