[En-Nut-Discussion] UdpGetError() is only conditionally defined

[Philipp Burch]

Hi all,

just found this in sys/socket.h:

#ifdef NUT_UDP_ICMP_SUPPORT
extern int NutUdpSetSocketError(UDPSOCKET * sock, uint32_t remote_addr, 
uint16_t remote_port, uint16_t error);
extern int NutUdpError(UDPSOCKET * sock, uint32_t * addr, uint16_t * port);
#endif

Why is there an #ifdef with ICMP for these basic functions? It is not 
present in the source, so the functions will always be compiled anyway.

Additionally, the doc still says "Todo: There is no similar call like 
NutTcpError() available for UDP."
Is something wrong with these functions or is this only a relict?

Thanks,

Philipp
