3,690在 GitHub 上查看liburing is a C library that provides a low-level wrapper for the Linux kernel io_uring interface. It serves as a programming interface for executing non-blocking disk and network operations and abstracts the system calls required to communicate with the Linux kernel. The library focuses on reducing system call overhead and context switching for high-throughput data processing. It implements mechanisms for shared ring buffers, zero-copy buffer registration, and fixed-file descriptor mapping to minimize internal lookup and reference counting overhead. The project covers asynchronous input and
Implements shared memory regions between user space and kernel space to exchange IO requests and completions without copying.
