Wrong. POSIX guarantees that you will have AT LEAST 256, but allows you to allocate much more (and some systems, such as GNU Hurd, have the goal of allowing as much as you would like). > I'm not even sure my toy FS violates POSIX. st_size contains the /on-disk/ > size of the symlink, not the length of the symlink in bytes. http://www.opengroup.org/onlinepubs/009695399/functions/lstat.html "For symbolic links, ... the st_size member shall contain the length of the pathname contained in the symbolic link." Your FS flat out violates this rule. - -- Don't work too hard, make some time for fun as well!
