[igraph] igraph BFS

[Ashwin Kumar]

Hi

I am using igraph 0.6 C interface. I need to work on trees, find the depth of the tree, and other statistics (average out degree, etc). I am also trying to use the igraph_bfs() function call. But, I am unable to find any documentation for this call in the HTML online help or the downloadable PDF. However, I do find an example implementation in the examples folder. 

Could anyone give me the function syntax, list of inputs and outputs? 

Thanks
