Good point, thanks. I'll change it immediately.

UDP provides a similar API as TCP does, but with some differences. The UDP 
interface is simpler since UDP is way simpler than TCP. The interface isn't 
documented yet, but the ideas are the same as the TCP interface and the code 
which implements the functions shouldn't be hard to follow. The functions are 
defined in the src/include/lwip/udp.h file. Note that the 0.4.2 udp.h and the 
CVS version until recently uses the old function names (udp_pcb_new() etc.).
