An application-defined function that passes unhandled exceptions to the debugger, if the process is being debugged. Otherwise, it optionally displays an Application Error message box and causes the exception handler to be executed. This function can be called only from within the filter expression of an exception handler.

Syntax

LONG WINAPI UnhandledExceptionFilter(
  __in  struct _EXCEPTION_POINTERS *ExceptionInfo
);

Parameters

ExceptionInfo [in]

A pointer to an EXCEPTION_POINTERS structure that specifies a description of the exception and the processor context at the time of the exception. This pointer is the return value of a call to the GetExceptionInformation function.

Return Value

The function returns one of the following values.

Remarks

If the process is not being debugged, the function displays an Application Error message box, depending on the current error mode. The default behavior is to display the dialog box, but this can be disabled by specifying SEM_NOGPFAULTERRORBOX in a call to the SetErrorMode function.

The system uses UnhandledExceptionFilter internally to handle exceptions that occur during process and thread creation.
