Testing the type of the structure? [message #30469]

Hi all.

Can I test which type of structure a certain variable (parameters) is?

For example, let's say i've got a variable a of type star:

a = {star, name:'sirius', size:2.1}

and a function that expects a star as input:

function is_a_star, s
; i would like to test here if s is of type 'star'
end

How can i test if parameter s is a star-structure?

I've found the obj_isa function but it only seems to work with objects. A
similar function for structures would be perfect.

Regards, Pepijn Kenter.
