Hiya,

Say I had a data structure containing 3 floats, such as:

struct threefloats
{
float x, y, z;
} float3f;

and I had a function which operates on an array of floats, such as:

void foo(float xyz[3]);

Is there anyway that I could modify the threefloats structure so as I could call foo with an argument of type threefloats? I know that I could make it return float by adding:

operator float()

to structure, but what about casting threefloats to an array such that x, y, and z in the threefloats structure gets put into the array for foo() to operate on.

Thanks,

Just cast a pointer to the structure to the type (float *), and then pass the resulting value as the argument to the function.

Yup, that did it ..thanks LM!!
