Mint

The mint function transfers an asset into the protocol, which begins accumulating interest based on the current Supply Rate for the asset. The user receives a quantity of aTokens equal to the underlying tokens supplied, divided by the current Exchange Rate.
SErc20
function mint(uint mintAmount) returns (uint)
msg.sender: The account which shall supply the asset, and own the minted aTokens.
mintAmount: The amount of the asset to be supplied, in units of the underlying asset.
RETURN: 0 on success, otherwise an Error code​
Before supplying an asset, users must first approve the aToken to access their token balance.
SEther
function mint() payable
msg.value [payable]: The amount of ether to be supplied, in wei.
msg.sender: The account which shall supply the ether, and own the minted aTokens.
RETURN: No return, reverts on error.

Erc20 underlying = Erc20(0xToken...);     // get a handle for the underlying asset contract
SErc20 aToken = SErc20(0x3FDA...);        // get a handle for the corresponding aToken contract
underlying.approve(address(aToken), 100); // approve the transfer
assert(aToken.mint(100) == 0);            // mint the aTokens and assert there is no error
