SignSignature() [1/2]

bool SignSignature	(	const SigningProvider &	provider,
		const CScript &	fromPubKey,
		CMutableTransaction &	txTo,
		unsigned int	nIn,
		const CAmount &	amount,
		int	nHashType,

Produce a satisfying script (scriptSig or witness).

Parameters

provider	Utility containing the information necessary to solve a script.
fromPubKey	The script to produce a satisfaction for.
txTo	The spending transaction.
nIn	The index of the input in txTo referring the output being spent.
amount	The value of the output being spent.
nHashType	Signature hash type.
sig_data	Additional data provided to solve a script. Filled with the resulting satisfying script and whether the satisfaction is complete.

Returns

True if the produced script is entirely satisfying fromPubKey.
