+ *
+ * While fwrite(), fputc(), fputs(), etc. all set the stream error flag
+ * on failure, the *printf functions are unique in that they can fail
+ * for reasons not related to the actual output itself. Among the possible
+ * reasons for failure which don't set the streams error indicator,
+ * SUSv3 lists EILSEQ, EINVAL, and ENOMEM.
+ *
+ * In some cases, it would be desireable to have a group of *printf()
+ * functions available that _always_ set the stream error indicator on
+ * failure. That would allow us to defer error checking until applet
+ * exit. Unfortunately, there is no standard way of setting a streams
+ * error indicator... even though we can clear it with clearerr().
+ *
+ * Therefore, we have to resort to implementation dependent code. Feel
+ * free to send patches for stdio implementations where the following
+ * fails.
+ *
+ * NOTE: None of this is threadsafe. As busybox is a nonthreaded app,
+ * that isn't currently an issue.
