So it looks like... an imperative programming language!
Some typical code:
int f(struct foo *foo)
{
...
err = foo_get_bar(foo, q, &bar);
if (err != 0)
...
err = bar_get_box(bar, p, &box);
if (err != 0)
...
...
err = box_frobnz(box, z, &a);
if (err != 0)
...
if (soanso)
{
err = box_grobny(box, y, &b);
if (err != 0)
...
}
...
}
The version with macros will look exactly the same, except you can omit
the '&', and they're usually upper case.

I think this is not a big deal, since the value is often then used more
than once. Even if not, the code may be more clear, if less concise.
[also helps debugging]
