libSceNpParty technical debt

Unknown function info

• sceNpPartyGetState and sceNpPartyGetStateAsUserA (libSceNpParty) - the 16-bit state, its NOT_IN_PARTY value 2 and the INVALID_ARGUMENT (0x80552504) error follow shadPS4's np_party.h and np_error.h (PS4); shadPS4 does not check for a null state, and whether the console needs an initialized party library first is not known. Not measured on a PS5
• sceNpPartyGetId, sceNpPartyGetMembersA, sceNpPartyGetMemberInfoA, sceNpPartyGetMemberSessionInfo, sceNpPartyGetMemberVoiceInfo and sceNpPartySendBinaryMessage (libSceNpParty) - the user is never in a party, so these return NOT_IN_PARTY (0x80552506, shadPS4's np_error.h) and write nothing, or INVALID_ARGUMENT for a null pointer; the signatures are from Orbital's type database. Like sceNpPartyGetState they do not require sceNpPartyInitialize, and the order of the null and party checks on the console is not known. Not measured on a PS5
• sceNpPartyInitialize, sceNpPartyTerminate, sceNpPartyCheckCallback and sceNpPartyRegisterHandlerA (libSceNpParty) - an initialized flag with ALREADY_INITIALIZED (0x80552502) and NOT_INITIALIZED (0x80552503) from shadPS4's np_error.h; the handlers are accepted but never called, since no party event can happen. Whether the console refuses a null initialize parameter, and which check comes first, is not known
• sceNpPartyCreate, sceNpPartyCreateA, sceNpPartyGetStateAsUser, sceNpPartyGetVoiceChatPriority, sceNpPartyJoin, sceNpPartyLeave, sceNpPartyRegisterPrivateHandler, sceNpPartySetVoiceChatPriority, sceNpPartyShowInvitationList, sceNpPartyShowInvitationListA and sceNpPartyUnregisterPrivateHandler (libSceNpParty) - Orbital has no prototypes for these and no credible ones were found. The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified
• sceNpPartyGetMembers, sceNpPartyGetMemberInfo and sceNpPartyRegisterHandler (libSceNpParty) - the signatures are from fpPS4 (PS4) and match their A variants, so they behave like them: no party, NOT_IN_PARTY from shadPS4, and handlers accepted but never called. How the console's non-A member structures differ from the A ones is not known, and nothing is written to them. Not measured on a PS5
