sceNetAdhocDiscover

"Discover" mode, used by a few games to find another console without the game itself scanning. It runs as a state machine the game steps every frame, like a utility dialog. Test: net/adhoc/discover (one console, nobody else around, so a successful discovery hasn't been observed).

typedef struct {
	u32 unknown1;
	char group[8];
	u32 unknown2;
	u32 result;   // written when it finishes: 1 = cancelled
} SceNetAdhocDiscoverParam;

int sceNetAdhocDiscoverInitStart(SceNetAdhocDiscoverParam *param); // NID 0x941B3877
int sceNetAdhocDiscoverUpdate(void);                                // NID 0x52DE1B97
int sceNetAdhocDiscoverGetStatus(void);                             // NID 0x944DDBC6
int sceNetAdhocDiscoverStop(void);                                  // NID 0xF7D13214
int sceNetAdhocDiscoverTerm(void);                                  // NID 0xA2246614
int sceNetAdhocDiscoverRequestSuspend(void);                        // NID 0xA423A21B

The library is available after loading the ADHOC net module. The test ran it with adhocctl initialized and not in a group.

• Before InitStart, GetStatus, Update, Stop and Term all return 0.
• InitStart(NULL) hangs the console.
• InitStart returns 0 and the status becomes IN_PROGRESS; shortly after, adhocctl's state becomes 4 (DISCOVER). A second InitStart while running gives 0x80411301.
• With nobody to find, it stays IN_PROGRESS (at least 10 s), with Update called every frame returning 0.
• Stop: adhocctl goes back to DISCONNECTED, the status becomes COMPLETED, result becomes 1 (cancelled), and adhocctl's handler gets a DISCONNECT event.
• RequestSuspend while discovering alone gives 0x80411303.
• Term returns 0, after which the status is 0.

PPSSPP: a stub that never finds anyone and never enters adhocctl state 4; InitStart while running and RequestSuspend return 0, and RequestSuspend ends it as cancelled.
