  - ### sysinfo

    int sysinfo(LibC.Sysinfo info)
    sysinfo() provides a simple way of getting overall system statistics. This is more portable than reading /dev/kmem.
    Parameters:
      `info` - A Sysinfo structure which will be populated
    Returns:
      On success, zero is returned. On error, -1 is returned, and errno is set appropriately.

  - ### statvfs

    int statvfs(String path, LibC.Statvfs buf)
    The function statvfs() returns information about a mounted filesystem.
    Parameters:
      `path` - the pathname of any file within the mounted filesystem.
      `buf` - a pointer to a statvfs structure
    Returns:
      On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
