Description

Points to the RTL run-time error handler.

In Delphi, ErrorProc is a procedure variable pointing to the run-time error handler. The standard ErrorProc procedure reports the run-time error and terminates the program.

The ErrorProc variable is retained primarily for compatibility with older code. Newer applications should not specify an alternate run-time error procedure using ErrorProc, as SysUtils uses this variable to convert run-time errors into exceptions.

If you use SysUtils in your program, it will force ErrorProc to its own routine and convert the run-time error into an exception. When a run-time library error occurs, the ErrorProc is called. The ErrorCode parameter contains the run-time error number and the ErrorAddr parameter contains the machine code address that caused the run-time error.
