How to obtain destination address of a mined block?

If the block is already mined, you could re-use code from 'getblock' and 'getrawtransaction'.
(shows address of a mined block in plain text if verbose==1,
block reward is usually (not sure if always) the 1st tx in the list from 'getblock')

It uses a public key from your reserved key pool, in a public-key script (NOT a pubkey-hash script -- there is no address which specifies this script type used in coinbase transactions). You can use 'getblocktemplate' to construct your own coinbase, with whatever script you desire.

In bitcoin-qt, seems that each mined block goes to new bitcoin address, first transaction output (mined block).
I was searching for "default address" for mined blocks, but do not seems possible. Createnewblock should be modified for this.

Coinbase outputs, as implemented by the reference client, are not one of the standard address formats.

What is your question, exactly?

How to obtain destination address of a mined block?

Similar to out address:

Code:

const CTxOut& txout = tx.vout[0];
txnouttype type;
vector addresses;
int nRequired;

if (ExtractDestinations(txout.scriptPubKey, type, addresses, nRequired)){
BOOST_FOREACH(const CTxDestination& addr, addresses){
printf("out_address:%s\n",CBitcoinAddress(addr).ToString().c_str());
}
