read, write, _read and _write on a guest socket descriptor went to the
host, which has no such descriptor, so sceKernelRead and sceKernelWrite
threw. They now reach the socket as recv and send without flags, with
the socket layer's errno (EAGAIN 35, EPIPE 32, EBADF 9), a zero-length
read returns 0 as dofileread does, and the two sceKernel forms return
the kernel error for the same cases. The host's SIGPIPE on EPIPE, a
write above INT_MAX bytes, readv, writev and the positioned forms are
recorded in TechnicalDebt.
OpenSSL's QUIC notifier signals its socketpair with write and read.

The status layout is shadPS4's OrbisGameLiveStreamingStatus2 (72
bytes). Live streaming is not supported, so the call reports that no
stream is on air, with an invalid user id; a null status throws.
Uncharted: Legacy of Thieves Collection (PPSA05684) stopped at sceGameLiveStreamingGetCurrentStatus2.
msync follows FreeBSD 11's kern_msync and vm_map_sync over the guest's
mappings as sceKernelVirtualQuery reports them: the address is rounded
down to the page, a range that wraps and MS_ASYNC with MS_INVALIDATE are
EINVAL, an unmapped start or page is ENOMEM, and length 0 checks the
mapping that holds the address. The guest has no file mappings, so a
successful call has nothing to write back. MS_INVALIDATE on a mapped
range throws, since FreeBSD's EBUSY for mlocked pages needs lock state
that is not tracked.
EVO-PLAYER PPSA99039 v0.11.0 imports it.

The IME panel cannot be open while sceImeOpen is unimplemented, so the
query returns SCE_IME_ERROR_NOT_OPENED and leaves the output untouched,
like sceImeSetCaret, sceImeSetText and sceImeSetTextGeometry. As with
sceImeSetCaret, the closed panel is reported before a null output.

shadPS4 returns success for an object id that was never reserved and the invalid-object error only for a released one; this library returns the error for both.

Both exports are imported by titles that link libSceAudio3d; without them the loader fails with an unresolved import before the title runs. Following the offline model, object attributes are validated but produce no audio and PortFlush drops the frames queued by sceAudio3dPortAdvance.
Pan follows the PS4 firmware 11.00 libSceNgs2.sprx: the speaker layout
from the init angles, then each param's angle and distance into a
volume matrix for the voice. Every param is checked before anything is
written, and angles too large to wrap throw. The pan functions are
exported from the existing Voice.cpp export block.

C17 has no binary prefix: with base 0 or 2, strtol("0b101", &end, base)
reads the subject "0", returns 0 and leaves end at the 'b'. With glibc
2.38 or later, g++ (which defines _GNU_SOURCE) binds std::strtoll,
strtoull, strtoul, strtoimax and strtoumax to the C23 __isoc23_*
functions, which accept 0b/0B: the Linux exports returned 5 and
consumed the whole string. The Windows UCRT already follows C17, so the
same guest call gave different results on the two hosts.
strtol, strtoul, strtoll, strtoull, _Stoull, strtoimax, strtoumax and
_Stoul now return 0 with the end pointer after the '0' when, after
white space and an optional sign, the text starts with 0b or 0B and a
binary digit, in base 0 or 2. Everything else still goes to the host
function. The scanf family's %i has the same glibc behaviour; it is
recorded in TechnicalDebt.

A port without a matrix sent source channel n to destination channel n, so a
mono voice reached only the left channel of a stereo mix. The PS4 firmware
11.00 libSceNgs2.sprx mixes such ports, and ports whose matrix levels were
never set, through a fixed channel map instead: mono reaches both stereo
channels at -3 dB and the centre of 5.1 and 7.1, stereo folds to mono at
-3 dB per side, and wider sources fold down with 0.5 and -3 dB gains. The map
was measured for every source width into 1, 2, 6 and 8 channels.

PPSA22520 routes its title music through port matrix 0 without setting the
matrix levels, so the music rendered silent. A matrix without levels now
mixes like a port without a matrix, source channel n to destination channel
n. The console's initial levels are unknown; the assumption is recorded in
TechnicalDebt.

FreeBSD vsyslog logs the complaint with LOG_ERR|LOG_CONS|LOG_PERROR|LOG_PID passed as the priority (0x23), not LOG_ERR.
Co-Authored-By: Claude <[email protected]>
ps5-opengl (PPSA99005) and ProsperoRadio (PPSA99001) import syslog
from libSceLibcInternal. Messages go to stderr with the priority, and
the format follows FreeBSD's vsyslog: %m expansion, masking of unknown
priority bits, LOG_USER as the default facility, errno preserved.

A title's descriptors are taken as never being terminals: a file or
pipe gets ENOTTY with the termios untouched, a socket gets what its
protocol answers a termios ioctl on FreeBSD (EADDRNOTAVAIL for AF_INET,
EOPNOTSUPP otherwise), and a closed or invalid descriptor EBADF.
tcsetattr gives EINVAL for an action other than TCSANOW, TCSADRAIN or
TCSAFLUSH, with or without TCSASOFT, before anything else, and EFAULT
for a null termios before the descriptor is checked; with TCSASOFT a
null termios throws, where FreeBSD's libc faults copying it. What the
console gives a title as descriptors 0 to 2 is unknown, as recorded in
TechnicalDebt.
