    payable
    returns (address[] memory assets, uint256[] memory assetAmounts)

The function to be called when a user wants to liquidate their position. Support liquidation with hot borrowing or not.

Parameters:

Name	Type	Description
_account	address	The address of the borrower
_prjInfo	struct Asset.Info	Information about the project token, including its address and type.
_lendingInfo	struct Asset.Info	Information about the lending token, including its address and type.
_lendingTokenAmount	uint256	The amount of lending tokens to be used for liquidation
priceIds	bytes32[]	An array of bytes32 price identifiers to update.
updateData	bytes[]	An array of bytes update data for the corresponding price identifiers.
buyCalldata	bytes[]	The calldata for buying the lending token from the exchange aggregator. If the calldata is empty, the liquidation will execute liquidation without hot borrowing.

getLiquidationAmountWithUpdatePrices (0x02dfa5d4)

function getLiquidationAmountWithUpdatePrices(
    address _account,
    address _projectToken,
    address _lendingToken,
    bytes32[] memory priceIds,
    bytes[] calldata updateData
) external payable returns (uint256 maxLA, uint256 minLA)

Returns the minimum and maximum liquidation amount for a given account, project token, and lending token after updating related token's prices.

Formula:

• MinLA = min(MaxLA, MPA)

• MaxLA = (LVR * CVc - THF * LVc) / (LRF * LVR - THF)

Parameters:

Name	Type	Description
_account	address	The account for which to calculate the liquidation amount.
_projectToken	address	The project token address.
_lendingToken	address	The lending token address.
priceIds	bytes32[]	An array of bytes32 price identifiers to update.
updateData	bytes[]	An array of bytes update data for the corresponding price identifiers.

Return values:

Name	Type	Description
maxLA	uint256	The maximum liquidation amount.
minLA	uint256	The minimum liquidation amount.
