Erick, I would pass the parameter by reference rather than by value. It's not considered good practice to pass data structures by value. (I don't think Simon was recommending that you pass the structure by value; he was recommending that you define the type of the parameter rather than using void *.)

static int myFunction(myEC_t *pApiErrCd);

Or if you don't want the function to be able to modify the parameter, code const.

static int myFunction(const myEC_t *pApiErrCd);

Inside the function use -> instead of .
intTest = pApiErrCd->EC_Fixed.Bytes_Provided;

And when you call the function, pass the address of the structure
myFunction(&ApiErrCd);
