varargs pragma - expanding a seq[cint]

[mantielero]

I am using `varargs` in the following example
    
    
    proc igraphsmall*(graph: ptr igrapht; n: igraphintegert; directed: 
igraphboolt;
                      first: cint): igrapherrort {.cdecl, varargs,
        importc: "igraph_small".}
    
    
    Run

How can I pass a `seq[cint]` to `first`?
