editor is giving the warning that this function may cause an infinite loop.

ANSWER
Answered 2018-Apr-30 at 16:48This will transfer all ether held by the contract to the owner’s address. There is no issue with the way you’re doing it.
The reason for the warning is because you are making a call out to another address. That address could itself be a contract with a custom defined transfer
or fallback function (if no transfer
method is defined). Since Remix doesn’t know what that implementation may do, it’ can’t estimate the gas usage. This isn’t a concern since transfer
calls are limited to a 2100 gas stipend.
You don’t need SafeMath
for that function since you’re not doing anything that can cause an overflow. However, in general, it’s a good idea to use it.
