Detailed Description

RTEMS Error Reporting.

Defines and externs for rtems error reporting

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 1:

#include <rtems.h>
#include <rtems/error.h>
rtems_error(0, "stray interrupt %d", intr);

Example 2:

if ((status = rtems_task_create(...)) != RTEMS_SUCCCESSFUL)
{
    rtems_error(status | RTEMS_ERROR_ABORT,
                "could not create task");
}

Example 3:

if ((fd = open(pathname, O_RDNLY)) < 0)
{
    rtems_error(RTEMS_ERROR_ERRNO, "open of '%s' failed", pathname);
    goto failed;
}
