Re: [B.A.T.M.A.N.] [PATCH 2/2] batctl: follow /proc to sysfs conversion & introduce input validation

The second thing is, I'm getting two harmless compile time warnings on the Debian stable VM here:

• bat-hosts.c:79/functions.c:174: warning: implicit declaration of function getline

getline(3) is a GNU extension. The man page says:

#define _GNU_SOURCE #include <stdio.h>

ssize_t getline(char **lineptr, size_t *n, FILE *stream);

I guess it compiles fine on uclibc without the _GNU_SOURCE, but glibc wants you to explicitly enable the extension so you know you are not POSIX compatible.

BTW: batctl has used this for a while now. Anybody had problems with this GNU extension? Is it available for all the C libraries used in embedded systems which use BATMAN?
