+.SH NAME
+\fBmitem_current\fP \- set and get current_menu_item
+.SH SYNOPSIS
+\fB#include <menu.h>\fP
+.sp
+\fBint set_current_item(MENU *\fImenu\fB, ITEM *\fIitem\fB);\fR
+.br
+\fBITEM *current_item(const MENU *\fImenu\fB);\fR
+.sp
+\fBint set_top_row(MENU *\fImenu\fB, int \fIrow\fB);\fR
+.br
+\fBint top_row(const MENU *\fImenu\fB);\fR
+.sp
+\fBint item_index(const ITEM *\fIitem\fB);\fR
+.SH DESCRIPTION
+The function \fBset_current_item\fP sets the current item (the item on which
+the menu cursor is positioned).
+\fBcurrent_item\fP returns a pointer to the
+current item in the given menu.
+.PP
+The function \fBset_top_row\fP 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
+\fBO_ROWMAJOR\fP option is toggled).
+The item leftmost on the given row
+becomes current.
+The function \fBtop_row\fP returns the number of the top menu
+row being displayed.
+.PP
+The function \fBitem_index\fP returns the (zero-origin) index of \fIitem\fP in
+the menu's item pointer list.
+.SH RETURN VALUE
+\fBcurrent_item\fP returns a pointer (which may be \fBNULL\fP).
+It does not set \fBerrno\fP.
+.PP
+\fBtop_row\fP and \fBitem_index\fP return \fBERR\fP (the general \fBcurses\fP
+error value) if their \fImenu\fP parameter is \fBNULL\fP.
+.PP
+\fBset_current_item\fP and \fBset_top_row\fP return one of the following:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_BAD_STATE
+Routine was called from an initialization or termination function.
+.TP 5
+.B E_NOT_CONNECTED
+No items are connected to the menu.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).
+.SH SEE ALSO
+\fBcurses\fP(3), \fBmenu\fP(3).
+.SH NOTES
+The header file \fB<menu.h>\fP automatically includes the header file
+\fB<curses.h>\fP.
+.SH PORTABILITY
+These routines emulate the System V menu library.
+They were not supported on
+Version 7 or BSD versions.
+.PP
+The SVr4 menu library documentation specifies the \fBtop_row\fP and
+\fBindex_item\fP error value as \-1 (which is the value of \fBERR\fP).
+.SH AUTHORS
+Juergen Pfeifer.
