- * 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 desirable 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().

- * Actually there is a portable way to set the error indicator. See below.
- * It is not thread-safe as written due to a race condition with file
- * descriptors but since BB is not threaded that does not matter. It can be
- * made thread-safe at the expense of slightly more code, if this is ever
- * needed in the future.
