The function <STRONG>set_current_item</STRONG> sets the current item (the item on which
the menu cursor is positioned). <STRONG>current_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 toggled). The item leftmost on the given row
becomes current. 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><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
<STRONG>current_item</STRONG> returns a pointer (which may be <STRONG>NULL</STRONG>). It does not set
<STRONG>errno</STRONG>.
<STRONG>top_row</STRONG> and <STRONG>item_index</STRONG> return <STRONG>ERR</STRONG> (the general <STRONG>curses</STRONG> error value) if
their <EM>menu</EM> parameter is <STRONG>NULL</STRONG>.
<STRONG>set_current_item</STRONG> and <STRONG>set_top_row</STRONG> return one of the following:
<STRONG>E_OK</STRONG> The routine succeeded.
<STRONG>E_BAD_ARGUMENT</STRONG>
Routine detected an incorrect or out-of-range argument.
<STRONG>E_BAD_STATE</STRONG>
Routine was called from an initialization or termination function.
<STRONG>E_NOT_CONNECTED</STRONG>
No items are connected to the menu.
<STRONG>E_SYSTEM_ERROR</STRONG>
System error occurred (see <STRONG>errno(3)</STRONG>).

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>).
