[igraph] Re: reading graph from files ??

[alex]

Hi,
thanx a lot it works now.
I have just one question, i have read in the documentation that the 
function:

   igraph_read_graphml(igraph_t *graph, File *instream, int index)

where index is the index of the graph to be load if the GraphML contains 
more than one graph.

So my question can i write more than one graph in graphML format because 
i have checked the documentation and i haven't found how to do it.

Thx for help
