gensym("foo") did the trick. Now I just call
`outlet_anything(x->outlist, gensym("foo"), 2, x->vec);` and it works.
Thanks!

Ahhh, it is similar to "atom_getsymbol", but also converts floats to
strings (instead of returning an empty symbol). I didn't even know
this function existed :) It's indeed easy to confuse with "gensym".
IMO, https://github.com/pure-data/externals-howto#gensym does not
really belong to the "atoms" sections...

Where do you see "atom_gensym"? I guess you confused it with
"atom_getsymbol" (which tries to interpret an atom as a symbol).
but how do I get a pointer to a "foo" symbol?
gensym("foo")

That's what I need, indeed. I can't get my head around how to create
the selector symbol though. The second argument to outlet_anything

symbol?
I've tried `t_symbol *s = atom_gensym("foo")` but I get a warning
the atom_gensym() expects a const t_atom *a, and when I pass `s` to
the second argument of outlet_anything and print the output, I get
"???" instead of "foo". This might be obvious, but it's quite
complicated to me.

You accidentally passed the outlet itself as the last argument
(t_atom *) to outlet_list().
Unfortunately, C only offers minimal type checking and happily
casts between unrelated pointer types. (With C++ this wouldn't
compile in the first place.) However, although this is legal in C,
all major compilers issue a warning ("-Wincompatible-pointer-types"
on GCC/Clang resp. "warning C4133" with MSVC).
Always check the compiler outputs for warnings!||

Now to your actual question:
I'm trying to output a list of values with a selector. For
example, "foo 1 2".
The function you're looking for is outlet_anything().
BTW, this is covered in the externals-howto:
https://github.com/pure-data/externals-howto#outlet-anything

a_type of the first element would be A_SYMBOL, and the other two
would be A_FLOAT, and after a list outlet is created in the new
method like this:
`x->outlist = outlet_new(x->x_obj, &s_list);`
I can output the list with a bang like this:
`outlet_list(x->outlist, &s_list, 3, x->outlist)`;
But Pd complains with this error:
```
print: listconsistency check failed: atom_string
consistency check failed: atom_string
consistency check failed: atom_string
```
What I would like, is to get the output of the object and route it
with [route foo]. How do I go about this?
