WebMay 31, 2024 · As seeplus says, it's easier if the buffer is unsigned char from the start. What happens when you do that? Good Luck !! :+) Edit: I am sure it says in the C++ standard that char values are bijectively mapped to the values 0 to 255. This means there is a 1 to 1 mapping of these values. So a cast from char to unsigned char should be fine.
