Hi all,

I'm just trying to compile osm2rdf (osm map data to GeoSPARQL), 
and found that they use sysconf(_SC_AVPHYS_PAGES) to get available 
memory:

int64_t available() {
  return sysconf(_SC_AVPHYS_PAGES) * sysconf(_SC_PAGE_SIZE);
}

Looking at sysconf(3) I can see that we do not have 
_SC_AVPHYS_PAGES. I searched for alternatives, but did not find 
any. 
I also did not find anything like "available" memory in 
sysconf(3).

So, can anyone tell me a FreeBSD alternative to 
sysconf(_SC_AVPHYS_PAGES)?

Thanks,

Mathias
