40 ITEM *current_item(const MENU *menu);
42 int set_top_row(MENU *menu, int row);
44 int top_row(const MENU *menu);
46 int item_index(const ITEM *item);
49 The function \fBset_current_item\fR sets the current item (the item on which
50 the menu cursor is positioned). \fBcurrent_item\fR returns a pointer to the
51 current item in the given menu.
53 The function \fBset_top_row\fR sets the top row of the menu to show the given
54 row (the top row is initially 0, and is reset to this value whenever the
55 \fBO_ROWMAJOR\fR option is toggled). The item leftmost on the given row
56 becomes current. The function \fBtop_row\fR returns the number of the top menu
59 The function \fBitem_index\fR returns the (zero-origin) index of \fIitem\fR in
60 the menu's item pointer list.
62 \fBcurrent_item\fR returns \fBNULL\fR on error.
64 \fBtop_row\fR and \fBitem_index\fR return \fBERR\fR (the general \fBcurses\fR
65 error value) on error.
67 \fBset_current_item\fR and \fBset_top_row\fR return one of the following:
70 The routine succeeded.
73 System error occurred (see \fBerrno\fR).
76 Routine detected an incorrect or out-of-range argument.
79 Routine was called from an initialization or termination function.
82 No items are connected to the menu.
84 \fBcurses\fR(3X), \fBmenu\fR(3X).
86 The header file \fB<menu.h>\fR automatically includes the header file
89 These routines emulate the System V menu library. They were not supported on
90 Version 7 or BSD versions.
92 The SVr4 menu library documentation specifies the \fBtop_row\fR and
93 \fBindex_item\fR error value as -1 (which is the value of \fBERR\fR).
