  64        Every menu item has a field  that  can  be  used  to  hold
  65        application-specific  data  (that is, the menu-driver code
  66        leaves it alone).  These functions get and set that field.

  71        The function  <STRONG>item_userptr</STRONG>  returns  a  pointer  (possibly
  72        <STRONG>NULL</STRONG>).  It does not set errno.
  73
  74        The <STRONG>set_item_userptr</STRONG> always returns <STRONG>E_OK</STRONG> (success).

  90        These routines emulate the System V  menu  library.   They
  91        were not supported on Version 7 or BSD versions.
  92
  93        The user pointer is a void pointer.  We chose not to leave
  94        it as a char pointer for SVr4 compatibility.
