User level file access

• Typical user level types and code:

  • pathnames: “/myfile”
  • file descriptors: fd = open(“/myfile”…)
  • attributes in struct stat: stat(“/myfile”, &mybuf), chmod, chown...
  • offsets: write, read, lseek
  • directory handles: DIR *dh = opendir(“/mydir”)
  • directory entries: struct dirent *ent = readdir(dh)
