I tried your code, but I get a compiler error: "sizeof applied to an incomplete type" for the rtems_bsdnet_config() line.

	The following code should do it.
	You just have to provide the correct interface name.
	  struct sockaddr_in addr;                                                                                                                                  
	  rtems_bsdnet_ifconfig("eth0", SIOCGIFADDR, &addr);                                                                                                        
	The IP address is then in addr.sin_addr.s_addr .
