VaultSetSize Event

Fires to resize a callback mode vault.

Syntax

cbvault.on('VaultSetSize', [callback])

Callback

The 'callback' is called when the 'VaultSetSize' event is emited.

function(e){ }

The argument 'e' has the following properties:

e.vaultHandle
e.newSize
e.resultCode

Remarks

This event fires when the class needs to resize 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 grow or shrink the vault specified by VaultHandle in order to reach the specified NewSize. When growing a vault, applications do not need to sanitize newly-allocated space.

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.
