CancelProc Class Documentation
class CancelProcNamespace:com::datalogics::PDFL
Detailed Description
A callback function used to abort an operation. A CancelProc() value is typically passed to a method that uses it to determine if an asynchronous operation should be ended.
At periodic intervals, the method calls the CancelProc. If the CancelProc returns a "true" boolean value, the method cancels the operation. If CancelProc returns false, the method allows the operation to continue. For example, CancelProc could be used to allow a user to click a Cancel button to end a function.
