+// Since 2014, the Rust runtime on Unix has set the `SIGPIPE` handler to
+// `SIG_IGN`. Applications have good reasons to want a different behavior
+// though, so there is a `#[unix_sigpipe = "..."]` attribute on `fn main()` that
+// can be used to select how `SIGPIPE` shall be setup (if changed at all) before
+// `fn main()` is called. See <https://github.com/rust-lang/rust/issues/97889>
+// for more info.
+//
+// The `sigpipe` parameter to this function gets its value via the code that
+// rustc generates to invoke `fn lang_start()`. The reason we have `sigpipe` for
+// all platforms and not only Unix, is because std is not allowed to have `cfg`
+// directives as this high level. See the module docs in
+// `src/tools/tidy/src/pal.rs` for more info. On all other platforms, `sigpipe`
+// has a value, but its value is ignored.
+//
+// Even though it is an `u8`, it only ever has 3 values. These are documented in
+// `compiler/rustc_session/src/config/sigpipe.rs`.

+//! # Random key generation
+//!
+//! This module wraps the RNG provided by the OS. There are a few different
+//! ways to interface with the OS RNG so it's worth exploring each of the options.
+//! Note that at the time of writing these all go through the (undocumented)
+//! `bcryptPrimitives.dll` but they use different route to get there.
+//!
+//! Originally we were using [`RtlGenRandom`], however that function is
+//! deprecated and warns it "may be altered or unavailable in subsequent versions".
+//!
+//! So we switched to [`BCryptGenRandom`] with the `BCRYPT_USE_SYSTEM_PREFERRED_RNG`
+//! flag to query and find the system configured RNG. However, this change caused a small
+//! but significant number of users to experience panics caused by a failure of
+//! this function. See [#94098].
+//!
+//! The current version changes this to use the `BCRYPT_RNG_ALG_HANDLE`
+//! [Pseudo-handle], which gets the default RNG algorithm without querying the
+//! system preference thus hopefully avoiding the previous issue.
+//! This is only supported on Windows 10+ so a fallback is used for older versions.

+# `unix_sigpipe`
+
+The tracking issue for this feature is: [#97889]
+
+[#97889]: https://github.com/rust-lang/rust/issues/97889
+
+---
+
+The `#[unix_sigpipe = "..."]` attribute on `fn main()` can be used to specify how libstd shall setup `SIGPIPE` on Unix platforms before invoking `fn main()`. This attribute is ignored on non-Unix targets. There are three variants:
+* `#[unix_sigpipe = "inherit"]`
+* `#[unix_sigpipe = "sig_dfl"]`
+* `#[unix_sigpipe = "sig_ign"]`
+
+## `#[unix_sigpipe = "inherit"]`
+
+Leave `SIGPIPE` untouched before entering `fn main()`. Unless the parent process has changed the default `SIGPIPE` handler from `SIG_DFL` to something else, this will behave the same as `#[unix_sigpipe = "sig_dfl"]`.
+
+## `#[unix_sigpipe = "sig_dfl"]`
+
+Set the `SIGPIPE` handler to `SIG_DFL`. This will result in your program getting killed if it tries to write to a closed pipe. This is normally what you want if your program produces textual output.
+
+### Example
+
+```rust,no_run
+#![feature(unix_sigpipe)]
+#[unix_sigpipe = "sig_dfl"]
+fn main() { loop { println!("hello world"); } }
+```
+
+```bash
+% ./main | head -n 1
+hello world
+```
+
+## `#[unix_sigpipe = "sig_ign"]`
+
+Set the `SIGPIPE` handler to `SIG_IGN` before invoking `fn main()`. This will result in `ErrorKind::BrokenPipe` errors if you program tries to write to a closed pipe. This is normally what you want if you for example write socket servers, socket clients, or pipe peers.
+
+This is what libstd has done by default since 2014. Omitting `#[unix_sigpipe = "..."]` is the same as having `#[unix_sigpipe = "sig_ign"]`.
+
+### Example
+
+```rust,no_run
+#![feature(unix_sigpipe)]
+#[unix_sigpipe = "sig_ign"]
+fn main() { loop { println!("hello world"); } }
+```
+
+```bash
+% ./main | head -n 1
+hello world
+thread 'main' panicked at 'failed printing to stdout: Broken pipe (os error 32)', library/std/src/io/stdio.rs:1016:9
