\function{IOperm}{(From,Num : Cadinal; Value : Longint)}{boolean}
{\var{IOperm}
sets permissions on \var{Num} ports starting with port \var{From} to
\var{Value}. The function returns \var{True} if the call was successfull,
\var{False} otherwise. \var{Value} is as in \var{}
{\em Remark:}
\begin{itemize}
\item This works ONLY as root.
\item Only the first \var{$03ff} ports can be set.
\item When doing a \seef{Fork}, the permissions are reset. When doing a
\seep{Execve} they are kept.
\end{itemize}

\function{Link}{(OldPath,NewPath : pathstr)}{Boolean}
{\var{Link} makes \var{NewPath} point to the same file als \var{OldPath}. The two files
then have the same inode number. This is known as a 'hard' link.
