Subject: [PATCH] Tools that take --dec=X option should only accept digits
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

|
Right now the argument of --dec is passed to atoi(3) which returns 0
|
|
on conversion error. Therefore, --dec=A was not rejected and was
|
|
equivalent to --dec=0 by mistake.
