2025-08-30Populate MSG struct for OpenBSD (#25076)Brandon Mercer
* update the MSG struct with the correct values for openbsd * add comment with link to sys/sys/socket.h --------- Co-authored-by: Brandon Mercer <bmercer@eutonian.com>
2025-08-27std.c: add correct SOMAXCONN for BSDsBrandon Black
Note the previous "28" here for openbsd was some kind of copy error long ago. That's the value of KERN.SOMAXCONN, which is an entirely different thing.

std.c.darwin: cleanup, expose everything in std.c
2025-08-20Add mlock syscalls to std.c and std.posixBrandon Black
Linux already gained the relevant syscalls and consts in #24473 The basic mlock() and munlock() are fairly universal across the *nix world with a consistent interface, but are missing on wasi and windows. The mlockall() and munlockall() calls are not as widely supported as the basic ones. Notable non-implementers include darwin, haiku, and serenity (and of course wasi and windows again). mlock2() is Linux-only, as are its MLOCK flags.
2025-08-20std.c.darwin: cleanup, expose everything in std.cJustus Klausecker
This mainly just moves stuff around. Justifications for other changes: * `KEVENT.FLAGS` is backed by `c_uint` because that's what the `kevent64` flags param takes (according to the 'latest' manpage from 2008) * `MACH_RCV_NOTIFY` is a legacy name and `MACH_RCV_OVERWRITE` is deprecated (xnu/osfmk/mach/message.h), so I removed them. They were 0 anyway and thus couldn't be represented as a packed struct field. * `MACH.RCV` and `MACH.SEND` are technically the same 'type' because they can both be supplied at the same time to `mach_msg`. I decided to still keep them separate because naming works out better that way and all flags except for `MACH_MSG_STRICT_REPLY` aren't shared anyway. Both are part of a packed union `mach_msg_option_t` which supplies a helper function to combine the two types. * `PT` is backed by `c_int` because that's what `ptrace` takes as a request arg (according to the latest manpage from 2015)

2025-07-30std.posix: Default ACCMODE to NONE for serenityLinus Groh
Unlike all other platforms where RDONLY is 0 it does not work as a default for the O flags on serenity - various syscalls other than 'open', e.g. 'pipe', return EINVAL if unexpected bits are set in the flags.

2025-07-14Add setsid to std.(c|posix)Brandon Black
The interface and errors for this seem to be very universal and generic. Note Linux already has this defined as a syscall as well.

2025-05-21libc: implement common `abs` for various integer sizes (#23893)David
* libc: implement common `abs` for various integer sizes * libc: move imaxabs to inttypes.zig and don't use cInclude * libc: delete `fabs` c implementations because already implemented in compiler_rt * libc: export functions depending on the target libc Previously all the functions that were exported were handled equally, though some may exist and some not inside the same file. Moving the checks inside the file allows handling different functions differently * remove empty ifs in inttypes Co-authored-by: Alex Rønne Petersen <alex@alexrp.com> * remove empty ifs in stdlib Co-authored-by: Alex Rønne Petersen <alex@alexrp.com> * libc: use `@abs` for the absolute value calculation --------- Co-authored-by: Alex Rønne Petersen <alex@alexrp.com>

2025-05-09std.posix: Add sigrtmin() and sigrtmax()Pat Tullmann
For C code the macros SIGRTMIN and SIGRTMAX provide these values. In practice what looks like a constant is actually provided by a libc call. So the Zig implementations are explicitly function calls. glibc (and Musl) export a run-time minimum "real-time" signal number, based on how many signals are reserved for internal implementation details (generally threading). In practice, on Linux, sigrtmin() is 35 on glibc with the older LinuxThread and 34 with the newer NPTL-based implementation. Musl always returns 35. The maximum "real-time" signal number is NSIG - 1 (64 on most Linux kernels, but 128 on MIPS). When not linking a C Library, Zig can report the full range of "rt" signals (none are reserved by Zig). Fixes #21189
2025-04-30c.zig: glibc/musl export 1024-bit sigset_tPat Tullmann
Export the sigset_t ops (sigaddset, etc) from the C library. Don't rely on the linux.zig defintions (which will be defined to use the kernel ABI). Move Darwin sigset and NSIG declarations into darwin.zig. Remove extraneous (?) sigaddset. The C library sigaddset can reject some signals being added, so need to defer to it.

2025-02-17std.Target: Remove functions that just wrap component functions.Alex Rønne Petersen
Functions like isMinGW() and isGnuLibC() have a good reason to exist: They look at multiple components of the target. But functions like isWasm(), isDarwin(), isGnu(), etc only exist to save 4-8 characters. I don't think this is a good enough reason to keep them, especially given that: * It's not immediately obvious to a reader whether target.isDarwin() means the same thing as target.os.tag.isDarwin() precisely because isMinGW() and similar functions *do* look at multiple components. * It's not clear where we would draw the line. The logical conclusion before this commit would be to also wrap Arch.isX86(), Os.Tag.isSolarish(), Abi.isOpenHarmony(), etc... this obviously quickly gets out of hand. * It's nice to just have a single correct way of doing something.

2025-02-09std.c: Use std.c.NI as the flags type in getnameinfoKarol Kosek
std.c.NI was never used in the source, so let's finally use it and make the function more clear! This is a breaking change, although a minor one: If you previously passed 0 here (meaning no flags), then now you have to pass an empty struct (.{}) instead. Otherwise, you probably used @bitCast() shenanigans here (like @bitCast(c.NI { .NUMERICHOST = true }) and that will still work, but you can also get rid of the @bitCast() now!

2025-02-09wasi: fix wasm-wasi-musl constantsPat Tullmann
Zig's copy of the `SYMLINK_{NO,}FOLLOW` constants from wasi-musl was wrong, as were the `IFIFO` and `IFSOCK` file type flags. Fix these up, and add comments pointing to exactly where they come from (as the wasi-musl source has lots of unused, different definitions of these constants). Add tests for the Zig convention that WASM preopen 3 is the current working directory. This is true for WASM with or without libc. Enable several fs and posix tests that are now passing (not necessarily because of this change) on wasm targets. Fixes #20890.

* fix merge conflicts * rename the declarations * reword documentation * extract FixedBufferAllocator to separate file * take advantage of locals * remove the assertion about max alignment in Allocator API, leaving it Allocator implementation defined * fix non-inline function call in start logic The GeneralPurposeAllocator implementation is totally broken because it uses global state but I didn't address that in this commit.
