VEX - Variable override

[samesami]

How do i write function that can override it variables like the &prim and &uv in xyzdist.

float  xyzdist(<geometry>geometry, vector origin, int &prim, vector &uv) 

 

float myProcess(float &space; float sideBar ) 
{
    float space=1;
    space = 15 * sideBar;
}

Since vex uses a call by reference way to call functions you do not need to do anything, just overwrite the values:

float bla(vector a; float b)
{
    a = set(1,2,3);
    b = 0.123;
    return 1.0;
}

vector tst = set(9,8,7);
float ff = .987;
bla(tst, ff);
printf("tst %f ff %f", tst, ff);

The printf should print the values overwritten in the bla() function.
