Re: [BProc] API changes from cm3 to cm4

[Greg W. <gw...@la...>]

Daniel,

None that I know of. The file clients/sys/bproc.h documents all the 
interfaces that are available.

In order to get the node number from the IP address, you now use:

   struct bproc_node_set_t list;

   if (bproc_nodelist(&list) == -1) {
     perror("bproc_nodelist");
     exit(1);
   }

   for (i=0; i < list.size; i++) {
     struct sockaddr_in *sin = (struct sockaddr_in *)&list.node[i].addr;
     if (memcmp(&addr, &sin->sin_addr, sizeof(addr)) == 0) {
       return list.node[i].node;
     }
   }

In order to look up a node by it's name, you first convert the name to 
an IP address, then use the above. If you're running the latest beonss 
then you can look up nodes using the names "master", "self", "n0", 
"n1", etc. using the standard gethostbyname() routines.

Regards,

Greg
