NAME

       menu_pattern - get and set a menu's pattern buffer

SYNOPSIS

       #include <menu.h>
       int set_menu_pattern(MENU *menu, const char *pattern);
       char *menu_pattern(const MENU *menu);

DESCRIPTION

       Every  menu  has  an  associated pattern match buffer.  As
       input events that are printable ASCII characters come  in,
       they  are  appended  to this match buffer and tested for a
       match, as described in menu_driver(3x).

       The function set_menu_pattern sets the pattern buffer  for
       the  given menu and tries to find the first matching item.
       If it succeeds, that item becomes  current;  if  not,  the
       current item does not change.

       The  function  menu_pattern  returns the pattern buffer of
       the given menu.

RETURN VALUE

       The function menu_pattern  returns  NULL  on  error.   The
       function  set_menu_pattern  may return the following error
       codes:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR
            System error occurred (see errno).

       E_BAD_ARGUMENT
            Routine detected an incorrect or  out-of-range  argu-
            ment.

       E_NO_MATCH
            Character failed to match.

NOTES

       The header file <menu.h> automatically includes the header
       file <curses.h>.

PORTABILITY

       These routines emulate the System V  menu  library.   They
       were not supported on Version 7 or BSD versions.
