Bypass function "out" parameters
delphi
Solution
You can create a wrapper:
procedure test(); overload;
var
SomeVar : string;
begin
test(SomeVar);
end;
Note: You'll also have to mark the other version with `overload`, or you can call your wrapper something other than `test`, and remove the `overload`.
Another option: declare a dummy variable somewhere (at the top of your unit, maybe):
var
DummyStr : string;
Then you don't have to declare a new variable every time you want to call the function.
test(DummyStr);
Problem
Some functions need a variable to send out a value. But sometimes I don't need that value and don't want to define a variable to use it as function `out` parameter. Like this: ``` procedure test(out SomeVar: string); begin //... end; ``` I want to execute this safely: ``` test; ```
