[gpsd-dev] from_sixbit() ...

[address@hidden]

Hallo,

i have looked at all other from_sixbit() call's in driver_ais.c .

Can someone please check all from_sixbit() call's too.

Most calls use bitlen-<startpos> as length parameter.

I, at least my, understanding, it should be (bitlen-<startpos>)/6+1 ....

The second part of ais message 21 

            from_sixbit((unsigned char *)bits,
                        272, (bitlen - 272)/6,
                        ais->type21.name+20);

If the call 

        from_sixbit((unsigned char *)bits,
                    43, 21, ais->type21.name);

is correct, ( I assume it is, see my previous mail), then the second call is 
not correct...
