onVaultDelete (event)

Fires to delete a callback mode vault.

Syntax

- (void)onVaultDelete:(NSString*)vault :(int*)resultCode;
func onVaultDelete(_ vault: String, _ resultCode: inout Int32)

Remarks

This event fires when the class needs to delete the callback mode vault identified by Vault.

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 delete the vault identified by Vault.

The Vault parameter contains an application-defined vault identifier (name, file path, etc.). The value of this parameter will always match the current value of the VaultFile property.

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.

Note: An application should not attempt to call class's methods from handlers of this event. Doing this is guaranteed to cause a deadlock.

Note: when a storage is opened concurrently in read-only mode by several applications using CBDrive or CBMemDrive class, the event will fire only in the first application. To prevent such a situation, always open a vault in read-write mode.
