Re: [igraph] Callback for long metric calculations.

[Gábor Csárdi]

It is available, but not documented. It is, however, easy to use, look
at progress.c in the source, and search for 'igraph_progress' in the
source files. If the callback returns a nonzero value, then the
calculation is interrupted and the error handler is called.

Not all functions use it, tough. In R you can turn it on by

igraph.par("verbose", TRUE)
