I'm looking at a way of creating a custom function in Vex any number of trailing params.

The closest reference I could find is here:

https://www.sidefx.com/docs/hdk/_h_d_k__vex_op.html [www.sidefx.com]

but I don't understand it.

eg.

void myFunc(int arr_i[]; string arr_s; string ...extra_params) {
   s@debug = extra_params[0];
}

here's a go lang example:

Go Variadic [gobyexample.com]

Is this possible? If so can someone give me a simple example?

Thanks in advance!

Hi traden1976!

Could you please elaborate a little bit, what you try to implement?

Hi Ommlet, I want to pass in an arbitrary amount of arrays to be populated. But it's more for the sake of curiosity VS being stuck on a problem.

Just wondering if it's actually possible.

thanks!

This way of declaring functions isn't supported. You should give it a string array instead.

You were on the right track, you'll have to compile a custom vex plugin using the HDK.

Edit:
never mind, variadic arguments don't support arrays.
