/*
* report errors and panics to RTEMS' stderr.
* Currently just used by RTEMS monitor.
*
* $Id$
*/
/*
* These routines provide general purpose error reporting.
* rtems_error reports an error to stderr and allows use of
* printf style formatting. A newline is appended to all messages.
*
* error_flag can be specified as any of the following:
*
* RTEMS_ERROR_ERRNO -- include errno text in output
* RTEMS_ERROR_PANIC -- halts local system after output
* RTEMS_ERROR_ABORT -- abort after output
*
* It can also include a rtems_status value which can be OR'd
* with the above flags. *
*
* EXAMPLE
* #include <rtems.h>
* #include <rtems/error.h>
* rtems_error(0, "stray interrupt %d", intr);
*
* EXAMPLE
* if ((status = rtems_task_create(...)) != RTEMS_SUCCCESSFUL)
* {
* rtems_error(status | RTEMS_ERROR_ABORT,
* "could not create task");
* }
*
* EXAMPLE
* if ((fd = open(pathname, O_RDNLY)) < 0)
* {
* rtems_error(RTEMS_ERROR_ERRNO, "open of '%s' failed", pathname);
* goto failed;
* }
