Do I need to free result of LeftStr/RightStr/etc?
« on: December 11, 2021, 07:04:47 pm »
I read the doc about LeftStr/RightStr, but does not get a clue if I need to free the returned/copied string. Or Pascal runtime automatically handles memory allocations?

Pascal strings are automatically memory managed.  C strings (pchar/pansichar/pwidechar) aren't.

That is a good question considering that it's one of the main advantages of Pascal over C ;)
