  50 <H2>NAME</H2><PRE>
  51        <STRONG>mitem_new</STRONG> - create and destroy menu items
  52
  53
  54 </PRE>
  55 <H2>SYNOPSIS</H2><PRE>
  56        <STRONG>#include</STRONG> <STRONG>&lt;menu.h&gt;</STRONG>
  57        ITEM *new_item(const char *name, const char *description);
  58        int free_item(ITEM *item);
  59

  61 </PRE>
  62 <H2>DESCRIPTION</H2><PRE>
  63        The function <STRONG>new_item</STRONG> allocates a new item and initializes
  64        it from the <STRONG>name</STRONG> and <STRONG>description</STRONG> pointers.  Please  notice
  65        that  the  item  stores  only the pointers to the name and
  66        description. Those pointers must be valid during the life-
  67        time of the item. So you should be very careful with names
  68        or descriptions allocated on the stack of some routines.
  69        The function <STRONG>free_item</STRONG> de-allocates an item. Please notice
  70        that  it  is  the  responsibility  of  the  application to
  71        release the memory for the name or the description of  the
  72        item.
  73
  74
  75 </PRE>
  76 <H2>RETURN VALUE</H2><PRE>
  77        The  function  <STRONG>new_item</STRONG>  returns  <STRONG>NULL</STRONG>  on error.  It sets
  78        errno according to the function's failure:
  79
  80        <STRONG>E_BAD_ARGUMENT</STRONG>
  81             Routine detected an incorrect or  out-of-range  argu-
  82             ment.
  83
  84        <STRONG>E_SYSTEM_ERROR</STRONG>
  85             System error occurred, e.g., malloc failure.
  86
  87        The function <STRONG>free_item</STRONG> returns one of the following:
  88
  89        <STRONG>E_OK</STRONG> The routine succeeded.
  90
  91        <STRONG>E_BAD_ARGUMENT</STRONG>
  92             Routine  detected  an incorrect or out-of-range argu-
  93             ment.
  94
  95        <STRONG>E_CONNECTED</STRONG>
  96             Item is connected to a menu.
  97
  98        <STRONG>E_SYSTEM_ERROR</STRONG>
  99             System error occurred (see <STRONG>errno</STRONG>).
