2021-08-13Fix warnings with Rust 1.46.0 - 1.51.0, inclusiveAlan Somers
These ranges of rustc are pickier about where to place an #[allow(unused_doc_comments)] attribute. It caused warnings when building for BSD-based targets.
2021-08-09Optionally implement TryFrom in libc_enum!Alan Somers
This saves code in several separate places that need to do this separately. At the same time, remove a few uses of mem::transmute that were implementing TryFrom or similar functionality. Issue #373
2021-04-04Use memoffset::offset_of instead of homegrown macroAlan Somers
The homegrown macro was fine in 2016, but at some point it technically became UB. The memoffset crate does the same thing, but avoids UB when using rustc 1.51.0 or later. Fixes #1415
2020-06-27Make sys::socket::sockaddr_storage a safe functionAlan Somers
It already fully validated its arguments, so there's no need for it to be `unsafe`.
2020-05-31Convert the crate to edition 2018Alan Somers
2020-05-17Add Redox support for most of the modulesXavier L'Heureux
Some things are not implemented yet in redox, so a lot of annotations were added to remove functions when compiling for redox. Those functions will hopefully be added in time, but for now it's better to have partial support than none. Blocked by https://github.com/rust-lang/libc/pull/1438
2019-09-04Simplify implementation of libc_enum! with vis metavariablesAlan Somers

2017-12-10Expand derives for all libc_bitflags! useBryant Mairs
2017-12-02Upgrade to Bitflags 1.0Bryant Mairs
The libc_bitflags! macro was replaced with a non-recursive one supporting only public structs. I could not figure out how to make the old macro work with the upgrade, so I reworked part of the bitflags! macro directly to suit our needs, much as the original recursive macro was made. There are no uses of this macro for non-public structs, so this is not a problem for internal code.
2017-08-27Support casting values in libc_enum!Bryant Mairs
2017-08-16Match libc_bitflags! syntax to upstream bitflags!Bryant Mairs
2017-07-10Add a libc_enum! macroBryant Mairs
This reduces the boilerplate necessary when wrapping libc constants into groups via enums
2017-07-04Allow casting a flag to a type in libc_bitflags!roblabla
This is necessary because certain flags in libc have different types, generally due to a mistake when adding the flags to the libc. See https://github.com/rust-lang/libc/pull/511 for an example of such a discrepency.

2016-11-18Fix Unix domain sockets.Alan Somers
There were multiple errors regarding Unix domain sockets: * UnixAddr::path assumed that gethostbyname and similar functions would include the terminating null as part of len. That is not universally true. In fact, POSIX only guarantees that len will be at least large enough to store the non-null-terminated path. So it could be larger or smaller than nix was assuming. Since abstract sockets' paths are not strings, we can't modify gethostbyname. Instead, I implemented the fix in UnixAddr::path and UnixAddr::new. I clarified the documentation too. * SockAddr::as_ffi_pair contained a Linuxism. * sockaddr_storage_to_addr forgot to adjust sun_len when creating a UnixAddr
2016-03-16Add libc_bitflags convenience macroKamal Marhubi
We define many bitflags types with values from the libc crate. Currently these look like this: bitflags!{ flags ProtFlags: libc::c_int { const PROT_NONE = libc::PROT_NONE, const PROT_READ = libc::PROT_READ, const PROT_WRITE = libc::PROT_WRITE, const PROT_EXEC = libc::PROT_EXEC, #[cfg(any(target_os = "linux", target_os = "android"))] const PROT_GROWSDOWN = libc::PROT_GROWSDOWN, #[cfg(any(target_os = "linux", target_os = "android"))] const PROT_GROWSUP = libc::PROT_GROWSUP, } } There's some repetition which is tedious. With the new macro, the above can instead be written libc_bitflags!{ flags ProtFlags: libc::c_int { PROT_NONE, PROT_READ, PROT_WRITE, PROT_EXEC, #[cfg(any(target_os = "linux", target_os = "android"))] PROT_GROWSDOWN, #[cfg(any(target_os = "linux", target_os = "android"))] PROT_GROWSUP, } } Thanks to Daniel Keep for the Little Book of Rust Macros, and for helping with this macro.
