* Change arguments of tun_gifindex from:
int tun_gifindex(struct tun_t *this, int *index)
to
int tun_gifindex(struct tun_t *this, __u32 *index)
solves:
../lib/tun.c: In function ‘tun_addaddr’:
../lib/tun.c:265: warning: pointer targets in passing argument 2 of
‘tun_gifindex’ differ in signedness
../lib/tun.c:88: note: expected ‘int *’ but argument is of type ‘__u32
*’
* handle system return code and returns -1 if system failed
solves:
../lib/tun.c: In function ‘tun_runscript’:
../lib/tun.c:895: warning: ignoring return value of ‘system’, declared
with attribute warn_unused_result
* do not dereference a pointer cast and use it as an lvalue
