I recently came across a code where

                uint32_t index = -1;

Is this safe to use the above.Assume that the code will have to be compiled across multiple Linux platforms and distributions.Or is it recommended to use a signed value? if I compare it against -1 somewhere in the program is it likely to compare -1 with 0xffffffff and throw an error or manifest some other strange behaviour.

What value do you expect? And how do you define safe? – SwiftMango Oct 08 '13 at 00:58
it is recommended coding practice? if I compare it against -1 somewhere in the program is it likely to compare -1 with 0xffffffff and throw an error etc – liv2hak Oct 08 '13 at 01:00
