Previous pageReturn to chapter overviewNext page   

Verifies that this is a valid kernel handle.







Code (Delphi)

function IsValidHandle(

const AHandle: THandle

): Boolean;



AHandle [in]

A handle to check.


Return value

If the AHandle is a valid kernel handle, the return value is True.


If the AHandle is not a valid kernel handle, the return value is False.



This function uses GetHandleInformation and DuplicateHandle to verify handle.


Use this routine with caution. It's heuristic.


Even when the function indicates that the handle is valid, a handle may be immediately closed by another thread.
