 *  Some functions in the library set the global variable @c errno when an
 *  error occurs. The file, @c <errno.h>, provides symbolic names for various
 *  error codes.
 *
 *  @warning The @c errno global variable is not safe to use in a threaded or
 *  multi-task system. A race condition can occur if a task is interrupted
 *  between the call which sets @c error and when the task examines @c
 *  errno. If another task changes @c errno during this time, the result will
 *  be incorrect for the interrupted task.
