pos_menu_cursor — position a menu's cursor
int pos_menu_cursor(const MENU *menu);
The function pos_menu_cursor restores the cursor to the current position associated with the menu's selected item. This is useful after curses routines have been called to do screen-painting in response to a menu select.
This routine returns one of the following:
The routine succeeded.
System error occurred (see errno).
Routine detected an incorrect or out-of-range argument.
The menu has not been posted.
The header file <menu.h> automatically includes the header file <curses.h>.
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
