posish provides safe wrappers to POSIX-ish libc APIs and syscalls.

posish is focused on functionality that isn't already provided by std or other low-level crates such as getrandom and errno. It prioritizes safe interfaces, including considering raw file descriptors to be equivalent to pointers in terms of making APIs unsafe, in the spirit of std::os::unix::io::FromRawFd::from_raw_fd being unsafe and RawFd not implementing AsRawFd/IntoRawFd.

posish is relatively low-level and does not support Windows; for higher-level and portable APIs to this functionality, see the system-interface, cap-std, and fs-set-times crates.
