address of struct variable?

[DavidDobson]

Hi, I was wondering if anyone could tell me how to pass the address of a specific variable in a struct?

Example:

typedef struct
{
  uint8_t     A;
  uint8_t     B;
  ExtAddr_t   C;
} stuff_t;

doSomething(&stuff_t.A);

Doing the above I get the warning: “passing argument 1 of 'doSomething‘ from incompatible pointer type”

Any pointers would be greatly appreciated

More like:

stuff_t stuff;
doSomething(&stuff.A);

The first does not compile since you can't take something from a blueprint.
Anyway, if you'd follow laserlight's advice and make doSomething take a uint8_t* pointer, then it should work fine.
