libjs

libc in JavaScript — libjs.

Usage

npm install libjs libsys

This library uses libsys to execute system calls from JavaScript. It expects your environment has libsys global object, in Node.js you can shim libsys as follows:

require('libsys/shim');

Examples

• Write to console
• Read from a file
• Run stat() on a file
• Create a basic server

Reference

• Synchronous system calls
  • Files: read, write, open, close, access, chmod, fchmod, chown, fchown, lchown, truncate, ftruncate, lseek, rename, fsync, fdatasync
  • Stats: stat, lstat, and fstat
  • Directories: mkdir, mkdirat, rmdir, getcwd, getdents64, readdir, and readdirList
  • Links: symlink, unlink, readlink, and link
  • Time: utime and utimes
  • Networking: socket, connect, bind, listen, accept, accept4, shutdown, send, sendto, recv, recvfrom, setsockopt
  • Process: getpid, getppid, getuid, geteuid, getgid, getegid, sched_yield, nanosleep
  • Events: fcntl, epoll_create, epoll_create1, epoll_wait, epoll_ctl, inotify_init, inotify_init1, inotify_add_watch, inotify_rm_watch
