Example

int ret;
int channel = 1;
canSettings settings;
settings.baudrate = 1000000;
settings.tseg1=5;
settings.tseg2=2;
settings.sjw=2;
settings.sam=1;
settings.flags = 0;

write("Set 1 MB");
ret = canSetConfiguration(channel, settings);

ret = canGetConfiguration(channel, settings);
if (ret)
{
    write("Settings: baud= %f, tseg1 = %d, tseg2= %d, sjw = %d, sam = %d, flags = 0x%x",
          settings.baudrate, settings.tseg1, settings.tseg2, settings.sjw, settings.sam, settings.flags);
