Description

Points to the assertion error-handler.

AssertErrorProc points to a routine that produces run-time error 227 in Delphi code. The SysUtils unit replaces it to cause an EAssertionFailed exception. If you do not use assertions, you can replace this with a method that does something else, such as call OutputDebugString to add messages to the event log (see the example).

The value of AssertErrorProc must be a procedure with the following signature:

procedure AssertErrorHandler(const Message, Filename: string; LineNumber: Integer; ErrorAddr: Pointer);
