@chapter Default Fatal Error Processing
@section Introduction
Upon detection of a fatal error by either the
application or RTEMS the fatal error manager is invoked. The
fatal error manager will invoke the user-supplied fatal error
handlers. If no user-supplied handlers are configured, the
RTEMS provided default fatal error handler is invoked. If the
user-supplied fatal error handlers return to the executive the
default fatal error handler is then invoked. This chapter
describes the precise operations of the default fatal error
handler.
@section Default Fatal Error Handler Operations
The default fatal error handler which is invoked by
the @code{rtems_fatal_error_occurred} directive when there is
no user handler configured or the user handler returns control to
RTEMS. The default fatal error handler performs the
following actions:
@itemize @bullet
@item disables processor interrupts,
@item places the error code in @b{r0}, and
@item executes an infinite loop (@code{while(0);} to
simulate a halt processor instruction.
