I haven't tried yet, but I was wondering if the PSPSDK supports the SOCK_RAW option. I want to send ARP packets from the application that I am writing, which would involve using SOCK_RAW
I don't really am into this, but i think i remember of a couple posts discussing it...and if i don't remember wrong the answer was "no, maybe". Try a quick search....
I tried a test program, and while I could open a socket with SOCK_RAW, it didn't act like a raw socket. So the answer seems to be no, the PSP doesn't support raw sockets.
