libuv is a multi-platform C library that provides support for asynchronous I/O based on event loops. It supports epoll(4) , kqueue(2) , Windows IOCP , Solaris event ports and Linux io_uring . It is primarily designed for use in Node.js but it is also used by other software projects. [ 3 ]

io_uring [a] (previously known as aioring) is a Linux kernel system call interface for storage device asynchronous I/O operations addressing performance issues with similar interfaces provided by functions like read()/write() or aio_read()/aio_write() etc. for operations on data accessed by file descriptors.
Python added support for SocketCAN in version 3.3. [2] An open source library python-can provides SocketCAN support for Python 2 and Python 3 [ 3 ] [ circular reference ] . Installing a CAN device requires loading the can_dev module and configuring the IP link to specify the CAN bus bitrate, for example:
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [33] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...
libuv; Kqueue equivalent for other platforms: on Solaris, Windows and AIX: I/O completion ports. Note that completion ports notify when a requested operation has completed, whereas kqueue can also notify when a file descriptor is ready to perform an I/O operation. on Linux: epoll system call has similar but not identical semantics.
Node.js uses libuv under the hood to handle asynchronous events. Libuv is an abstraction layer for network and file system functionality on both Windows and POSIX-based systems such as Linux, macOS, OSS on NonStop, and Unix. Node.js relies on nghttp2 for HTTP support.
