Subject: [PATCH] mib.c: allow unsigned integers to have an extra byte
|
||||
|
||||
The extra byte can be needed when encoding huge unsigned numbers (i.e. 0x80000000 or higher). In this case, during encoding we need an extra byte to make sure clients decoding as signed int do not get negative numbers. For further details, see commit 949ae648
