Description
The class of OLE error codes.
Rather than instantiate an error directly with make, you can also use the convenience function check-ole-status, or ole-error to create and signal an instance of this class.
You can use the following accessor functions on the error object:
ole-error-status-
Returns the low-level status code.
ole-error-context-
Returns the name of the function that returned the code.
ole-error-instance-
Returns the interface that the function was acting upon.
ole-error-args-
Returns a
<sequence>of additional function arguments which the code that calledole-errororcheck-ole-statusmight have supplied in its call.
