Here's another problem. When we change the OS not only must we setup the compiler, environment and such but sometimes an OS API could be deprecated or removed. You made mention of a possible OS change so that's a possibility. You obtained this code from somewhere. Go back there and see if they updated it for your new OS.

const
means constant. that it won't be changed anywhere within the scope where it is implemented. if a function takes, for example, a pointer to a "

char" argument, you know you can pass in a string to that argument and your string will not be modified by the function.

Const
just means that the function is unable to modify the value. Of course if you don't want to change the value, then just don't change it!
Const

is used to make something constant, meaning that its value should never change, as such you cant dynamically allocate an array for a constant value. It has to either be a regular

`
const
` doesn't mean that the object is stored in read-only memory, though that's a possibility. All `
const
` means is that the compiler will enforce read-only uses of the variable. So you can attempt to subvert the type system by casting away `
const
` and it'll probably work, but there's no guarantee.
