ExtractDestination()

bool ExtractDestination	(	const CScript &	scriptPubKey,
		CTxDestination &	addressRet,
		bool	fColdStake = false
	)

Parse a standard scriptPubKey for the destination address.

Assigns result to the addressRet parameter and returns true if successful. For multisig scripts, instead use ExtractDestinations. Currently only works for P2PK, P2PKH, P2SH and P2CS scripts.

ExtractDestinations()

bool ExtractDestinations	(	const CScript &	scriptPubKey,
		txnouttype &	typeRet,
		std::vector< CTxDestination > &	addressRet,
		int &	nRequiredRet
	)

Parse a standard scriptPubKey with one or more destination addresses.

For multisig scripts, this populates the addressRet vector with the pubkey IDs and nRequiredRet with the n required to spend. For P2CS addressRet is populated with the staker and owner IDs and nRequiredRet is set to 2. For other destinations, addressRet is populated with a single value and nRequiredRet is set to 1. Returns true if successful.

GetScriptForDestination()

CScript GetScriptForDestination

(

const CTxDestination &

dest

)

Generate a PIVX scriptPubKey for the given CTxDestination.

Returns a P2PKH script for a CKeyID destination, a P2SH script for a CScriptID, and an empty script for CNoDestination.

Solver()

bool Solver	(	const CScript &	scriptPubKey,
		txnouttype &	typeRet,
		std::vector< std::vector< unsigned char > > &	vSolutionsRet
	)

Parse a scriptPubKey and identify script type for standard scripts.

If successful, returns script type and parsed pubkeys or hashes, depending on the type. For example, for a P2SH script, vSolutionsRet will contain the script hash, for P2PKH it will contain the key hash, etc.

Parameters

[in]	scriptPubKey	Script to parse
[out]	typeRet	The script type
[out]	vSolutionsRet	Vector of parsed pubkeys and hashes

Returns

True if script matches standard template
