-<H2>NAME</H2><PRE>
- <STRONG>mitem_current</STRONG> - set and get current_menu_item
-
-
-</PRE>
-<H2>SYNOPSIS</H2><PRE>
- <STRONG>#include</STRONG> <STRONG>&lt;menu.h&gt;</STRONG>
- int set_current_item(MENU *menu, const ITEM *item);
- ITEM *current_item(const MENU *menu);
- int set_top_row(MENU *menu, int row);
- int top_row(const MENU *menu);
- int item_index(const ITEM *item);
-
-
-</PRE>
-<H2>DESCRIPTION</H2><PRE>
- The function <STRONG>set_current_item</STRONG> sets the current item (the
- item on which the menu cursor is positioned). <STRONG>cur-</STRONG>
- <STRONG>rent_item</STRONG> returns a pointer to the current item in the
- given menu.
-
- The function <STRONG>set_top_row</STRONG> sets the top row of the menu to
- show the given row (the top row is initially 0, and is
- reset to this value whenever the <STRONG>O_ROWMAJOR</STRONG> option is tog-
- gled). The item leftmost on the given row becomes cur-
- rent. The function <STRONG>top_row</STRONG> returns the number of the top
- menu row being displayed.
-
- The function <STRONG>item_index</STRONG> returns the (zero-origin) index of
- <EM>item</EM> in the menu's item pointer list.
-
-
-</PRE>
-<H2>RETURN VALUE</H2><PRE>
- <STRONG>current_item</STRONG> returns <STRONG>NULL</STRONG> on error.
-
- <STRONG>top_row</STRONG> and <STRONG>item_index</STRONG> return <STRONG>ERR</STRONG> (the general <STRONG>curses</STRONG>
- error value) on error.
-
- <STRONG>set_current_item</STRONG> and <STRONG>set_top_row</STRONG> return one of the follow-
- ing:
-
- <STRONG>E_OK</STRONG> The routine succeeded.
-
- <STRONG>E_SYSTEM_ERROR</STRONG>
- System error occurred (see <STRONG>errno</STRONG>).
-
- <STRONG>E_BAD_ARGUMENT</STRONG>
- Routine detected an incorrect or out-of-range argu-
- ment.
-
- <STRONG>E_BAD_STATE</STRONG>
- Routine was called from an initialization or termina-
- tion function.
-
- <STRONG>E_NOT_CONNECTED</STRONG>
- No items are connected to the menu.

-<H2>NOTES</H2><PRE>
- The header file <STRONG>&lt;menu.h&gt;</STRONG> automatically includes the header
- file <STRONG>&lt;curses.h&gt;</STRONG>.
-
-
-</PRE>
-<H2>PORTABILITY</H2><PRE>
- These routines emulate the System V menu library. They
- were not supported on Version 7 or BSD versions.
-
- The SVr4 menu library documentation specifies the <STRONG>top_row</STRONG>
- and <STRONG>index_item</STRONG> error value as -1 (which is the value of
- <STRONG>ERR</STRONG>).
