Uhm, I have found a solution :-) The problem is that C (or GCC) can
only change variable out of function using *variable=value
construct. This *variable syntax is essential. This is the only
possible way of using pointer to pass information outside function.
But this way it is only possible to

That's how C works - everything is passed to the function by value, so
when you pass a pointer, you just pass a value which is an address.

Hmm, things seems to be more suble :-)
I have tried a trick with using int *a; fun(int* a); and it indeed
works but the address is trimmed no matter what type a is (int*,
long*, void*) and this causes problems.
21 int a1=0, a2=0;
(gdb) s
22 double *a3;
(gdb)
23 a3=NULL;
(gdb)
With current design of OpenOCD it is impossible to queue read
operations as results are returned using single pointers, the read
operation needs to be performed inside of a function that will return
a result, otherwise we can only get a value given at queue time but
not a flush time.

Luckily it only requires minor change of SWD_OPERATION_ENQUEUE into
SWD_OPERATION_EXECUTE parameter :-P :-)

Hey,
I have some problems with pointers and need some support plz ;-)
int swd_bus_read_ack(swd_ctx_t *swdctx, swd_operation_t operation, char **ack){
swd_cmd_enqueue_miso_ack(swdctx, ack);
}

if (swdctx==NULL) return

I'm not sure I understand what the problem is, but I can give some general
hints.

naah this is only typo in mind-shortcut, code builds well, but i dont
