  <para>
   <function>proc_close</function> is similar to <function>pclose</function>
   except that it only works on processes opened by
   <function>proc_open</function>.
   <function>proc_close</function> waits for the process to terminate, and
   returns its exit code.  Open pipes to that process are closed
   when this function is called, in
   order to avoid a deadlock - the child process may not be able to exit
   while the pipes are open.
