GitHub - gnosis/MultiSigWallet: Allows multiple parties to agree on transactions before execution.

function external_call(address destination, uint value, uint dataLength, bytes data) 
 private 
 returns (bool) 
{
    bool result;
    assembly {
        let x := mload(0x40)   
        let d := add(data, 32) 
        result := call(
            sub(gas, 34710),             
            destination,
            value,
            d,
            dataLength,        
            x,
            0
        )
    }
    return result;
}

call opcode를 활용. 거기에 필요한 인자값을 지정해서 넣어줌
