/* Used to be a blanket #include <tcpip.h> - see libcglue's own
 * sys/socket.h for the full story on why that header is real,
 * pre-lwip-migration technical debt that conflicts with ps2ip's real
 * lwip headers. struct hostent/struct addrinfo are only ever used by
 * pointer below - real, file-scope forward declarations instead
 * (same reasoning, and the same "declared inside parameter list"
 * hazard, as ps2sdkapi.h's own - see that file's comment on why a
 * shared, real tag is needed rather than none at all). */
/* Error codes, numbered like lwip's so values from the ps2ip stack pass through unchanged. */
