[GRASS-dev] d.legend: -2147483648 -> null?

[Markus Neteler]

Hi,

using d.rast.leg (d.legend) on a NO DATA integer map, it prints "-2147483648"
instead of null.

Below dirty hack cures the problem - how to do it correctly?

[neteler at markus d.legend]$ svn diff

sprintf(buff, "null");

                        strcat(buff, ")");
                }

thanks
