If I understand you correctly, you are saying that you have a *A on the Go side, and you want it to call C code, and you want the C code to call back into Go, and when you call back you want to have the same *A you started with. If that is accurate, then one way or another you need pass the *A from Go to C. There is no magic way that you can call into C and then back to Go and somehow know which *A you had to begin with, any more than you could do it if you called from Go to Go without passing the *A.
