  50        <STRONG>menu_pattern</STRONG> - get and set a menu's pattern buffer
  51
  52
  53 </PRE>
  54 <H2>SYNOPSIS</H2><PRE>
  55        <STRONG>#include</STRONG> <STRONG>&lt;menu.h&gt;</STRONG>
  56        int set_menu_pattern(MENU *menu, const char *pattern);
  57        char *menu_pattern(const MENU *menu);

  61 <H2>DESCRIPTION</H2><PRE>
  62        Every  menu  has  an  associated pattern match buffer.  As
  63        input events that are printable characters come  in,  they
  64        are  appended to this match buffer and tested for a match,
  65        as described in <STRONG><A HREF="menu_driver.3x.html">menu_driver(3x)</A></STRONG>.
  66
  67        The function <STRONG>set_menu_pattern</STRONG> sets the pattern buffer  for
  68        the  given menu and tries to find the first matching item.
  69        If it succeeds, that item becomes  current;  if  not,  the
  70        current item does not change.
  71
  72        The  function  <STRONG>menu_pattern</STRONG>  returns the pattern buffer of
  73        the given <EM>menu</EM>.
  74
  75
  76 </PRE>
  77 <H2>RETURN VALUE</H2><PRE>
  78        The function <STRONG>menu_pattern</STRONG> returns a pointer, which is <STRONG>NULL</STRONG>
  79        if the <EM>menu</EM> parameter is <STRONG>NULL</STRONG>.  Otherwise, it is a pointer
  80        to a string which is empty if no pattern has been set.  It
  81        does not set errno.
  82
  83        The  function  <STRONG>set_menu_pattern</STRONG>  may  return the following
  84        error codes:
  85
  86        <STRONG>E_OK</STRONG> The routine succeeded.
  87
  88        <STRONG>E_BAD_ARGUMENT</STRONG>
  89             Routine detected an incorrect or  out-of-range  argu-
  90             ment.
  91
  92        <STRONG>E_BAD_STATE</STRONG>
  93             Routine was called from an initialization or termina-
  94             tion function.
  95
  96        <STRONG>E_NOT_CONNECTED</STRONG>
  97             No items are connected to menu.
  98
  99        <STRONG>E_NO_MATCH</STRONG>
 100             Character failed to match.
 101
 102        <STRONG>E_SYSTEM_ERROR</STRONG>
 103             System error occurred (see <STRONG>errno</STRONG>).
