RECIP CARBURETOR TEMPERATURE returns 0?

[dragonflightdesign 98]

Got to be me, but the following piece of code always returns zero at all altitudes and throttle settings. Just on the offchance I tried the SINT32 slot too but that also returned zero. Anyone any idea what I've missed/done wrong?

 

//**************************************************************************
//  Carburetor air temperature
//**************************************************************************
double getCarbTemp(double engine)
{
    double degC=0;
    execute_calculator_code("(A:RECIP CARBURETOR TEMPERATURE,engine)", &degC, NULL, NULL);
    return degC;
}

Maybe this:

double getCarbTemp(int engine)
{
    double degC = 0;
    char var_name[48] = { 0 };
    sprintf_s(var_name, "(A:RECIP CARBURETOR TEMPERATURE:%i, celsius)", engine);
    execute_calculator_code(var_name, &degC, NULL, NULL);
    return degC;
}

You need to separate the index from the name with a colon, and you need units for an xml A:var.

Arghhh!! It had to be a typo, didn't it?? Thanks Doug.

That's definately gone into the 'if it doesn't work, try Doug's method' pile. Doug's Method (capitalised and bold) just fixed a long-standing problem with GENERAL ENG GENERATOR SWITCH too.
