Subject: SWIG and "connect"? [Was: SWIG and char * parameters]

D'OH!  Now that Brett has pointed out why my oversimplified example was 
failing I've gone back and found out the problem was more subtle than I 
thought:

When I name a function "connect" it behaves differently than if I name it 
"connectTo".  As far as I'm aware, connect isn't a reserved word in either 
language, and no warnings are generated when I compile this.

Incidentally, I'm doing this to try to make Ruby an RPC client.  Is there a 
better way of doing this, other than SWIG?  The only RPC<->Ruby connections 
I've found are for XML-RPC.

int connectTo(char *host) {
  printf("Connecting to %s\n", host);
  global_client_ptr = clnt_create (host, MAXWELLPROG, V1, "udp");
  if (global_client_ptr == NULL) {
    clnt_pcreateerror (host);
    return 0;
  }
  return 1;
}

int connect(char *host) {
  printf("Connecting to %s\n", host);
  global_client_ptr = clnt_create (host, MAXWELLPROG, V1, "udp");
  if (global_client_ptr == NULL) {
    clnt_pcreateerror (host);
    return 0;
  }
  return 1;
}

Thanks again,
