This works for a literal, but the author was probably thinking of "print a string that comes from somewhere else" where you do the first thing to avoid format characters to be interpreted.

Could be. But wouldn't then displayln() require the same string placeholder? Be it "%s", or "{1}" or someting else.

displayln uses the massive _Generic in display_format to supply a large number of formatters automatically. [0]

I see. So when for a char pointer one needs to do

        printf("%p\n", v);

the Generic call must look like this

        displayln((const void *)v);

is it really better?

[shakna]

Or you could have the pointer be a pointer before you feed it to the function.

    void* v;
    v = ...;

    ...

    displayln(v);

The amount of ellipsis shows that your solution is just as heavy weight.
