accept after select for RTNet/TCP

[Per Oberg <pero@wolfram.com>]

Hi 

I'm currently porting parts of an application that uses some TCP during startup to Xenomai. I have a working example of a TCP server but i cannot make the "select" part work.

If I do 

fd = __COBALT(accept(list_fd, (struct sockaddr *) &client_addr, &client_len)))

without the select part it works. If I do a select before it returns  "Invalid argument". 

The "select" part:
------------------------------------
fd_set in_fds;
FD_ZERO(&in_fds);
FD_SET(list_fd, &in_fds);
int selRet = __COBALT(select(list_fd + 1, &in_fds, 0, 0, 0));
(FD_ISSET(list_fd, &in_fds))
{
  printf("list_fd (%i)  is in FDSET\n", list_fd);
}
------------------------------------

The program works when compiled for regular linux.
Is select for TCP RTNet a no no ?
