Flag 0x4 isn't ever assigned in the code. Flags 0x40 and 0x80 are also not used, even though they are assgined in the input events by default along with 0x20. This is likely because that code section was inherited from the Wii, where these flags are used for poll errors. | |||
Contrary to the Wii sockets, the 3DS doesn't have POLLERR or POLLHUP, so poll shouldn't be relied on when checking for socket errors. | |||
