How to pass msg.value as an argument?

Question

I am trying to implement deposit functionality in my contract in the sense whoever calls the function below needs to deposit some ether. For example:

Contract A calls the function below and again, Contract A needs to deposit some ether.

I can do this with the remix interface by passing "VALUE". But I want to pass this variable as an argument.

Here is what

event Deposit(address sender, uint amount, uint balance);

function deposit(uint testAmount) public payable {
    testAmount = msg.value; // GIVES ERROR
    emit Deposit(msg.sender, testAmount, address(this).balance);
} 

function doWork(int job_id, uint amount) public payable{
   deposit(amount);
}

Answer 1

Your issue is that you're trying to reassign to a parameter, which you don't need to do. This is likely the simplest change you could make to get this to work:

event Deposit(address sender, uint amount, uint balance);

function deposit() public payable {
    emit Deposit(msg.sender, msg.value, address(this).balance);
} 

function doWork(int job_id, uint amount) public payable{
   deposit();
}
