libSceNpCommon technical debt

Unknown function info

The 34 declarations below use names mapped from the local libSceNpCommon.sprx export table. Each NID was verified against that table and recomputed from its name with tools/nid_names.py. The public PS5 3.20 libSceNpCommon export list contains all 150 symbol names. No prototype or behavior is claimed. Each declaration uses the no-parameter unknown-signature convention solely for import resolution and throws if called.

Functional

• Online ID and NpId utilities (libSceNpCommon) - sceNpCmpOnlineId, sceNpCmpNpIdInOrder, sceNpGetPlatformType and sceNpIntIsValidOnlineId are not measured on a console; their signatures, checks and results follow shadPS4, including the platform tags read from opt[4..7] and the 3 to 16 character online ID rule.
• Mutex, condition and thread wrappers (libSceNpCommon) - the sceNpMutex*, sceNpLwMutex*, sceNpCond* and sceNpJoinThread wrappers forward to the libkernel scePthread* calls as in shadPS4 and are not measured on a console. Only EBUSY from try-lock and ETIMEDOUT from a timed wait are mapped to NP errors; every other kernel error is returned unchanged. The flags argument of sceNpCondInit is ignored.
• sceNpGetSdkVersion (libSceNpCommon) - writes the libkernel system software version as major.minor into an 8-byte buffer without checking it, as shadPS4 does; that version is the fixed 1.00, not the SDK version a title was built with.
• The exports in Runtime.cpp and Strings.cpp follow libSceNpCommon.sprx from firmware 13.60, read from disassembly and not measured on a console.
• sceNpCreateThread always applies an explicit priority when one is given; the firmware picks between explicit and inherited scheduling from the title's compiled SDK version, which is not available here.
• sceNpCalloutStartOnCtx and sceNpCalloutStartOnCtx64 look for the callout in the queue before writing it and return 0x80558006 with the entry and the queue unchanged. Firmware 13.60, read from disassembly and not measured on a console, clears and fills the entry before it takes the lock and checks the queue, so restarting a queued callout returns the same error but drops every callout queued after it.
• sceNpArchInit and sceNpArchTerm keep a reference count under a lock and create the global heap once. Firmware 13.60, read from disassembly and not measured on a console, uses no lock and never sets its count on the first call, so every call made while the count is zero creates the heap again, and a call to sceNpArchTerm at zero destroys the heap and leaves the count negative.
• sceNpGetRandom draws from a 32-bit Mersenne Twister seeded once per process; the console uses SFMT-19937 with a seed set inside the module, so the sequences differ.
• sceNpHeapShowStat and sceNpDbgDumpBinary print the same information as the console in a different layout.
• The string-to-integer exports clear errno before parsing; the firmware reads whatever errno held before the call when the result saturates.
• The integer-to-string exports return 0x80558008 when the hexadecimal prefix does not fit; the firmware writes the prefix without checking the size. The base64 decoders treat bytes above 0x7F as invalid; the firmware indexes its table with them as signed values. sceNpUtilJsonGetOneChar checks that a \u escape and a surrogate pair fit in the input; the firmware reads past it.
• sceNpUtilGetNpDebug, sceNpUtilGetNpTestPatch, sceNpUtilGetTrcNotify, sceNpUtilGetIgnoreNpTitleId, sceNpUtilGetFakeDisplayNameMode, sceNpUtilGetWebTraceSetting, sceNpUtilGetWebApi2FakeRateLimit, sceNpUtilGetWebApi2FakeRateLimitTarget, sceNpUtilGetFakeRateLimit, sceNpUtilGetDbgCommerce, sceNpUtilGetSystemLanguage, sceNpUtilGetEnv, sceNpUtilGetDateSetAuto and sceNpUtilGetShareTitleCheck read system and debug registry keys through libSceRegMgr, whose sceRegMgrNonSysGetInt and string reads still throw; they throw until those exist.
• sceNpOpenSema and sceNpCloseSema forward to the libkernel open and close calls for named semaphores, which still throw.
• sceNpSetPlatformType, sceNpIntGetPlatformType, sceNpIntSetPlatformType, sceNpUtilCanonicalizeNpIdForPs4, sceNpUtilCanonicalizeNpIdForPsp2, sceNpUtilJidToNpId and sceNpGetNavSdkVersion depend on console platform tags, network domain names or a version string of the console; they throw.
• sceNpJsonParse, sceNpJsonParseInit, sceNpJsonParseBuf, sceNpJsonParseBufInit, sceNpJsonParseEx, sceNpJsonParseExInit and the sceNpServerErrorJson exports are a streaming, schema-checked JSON parser whose event and error rules are not yet specified; they throw.
