</PRE>
<H2>NAME</H2><PRE>
       <STRONG>menu_pattern</STRONG> - get and set a menu's pattern buffer


</PRE>
<H2>SYNOPSIS</H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;menu.h&gt;</STRONG>
       int set_menu_pattern(MENU *menu, const char *pattern);
       char *menu_pattern(const MENU *menu);


</PRE>
<H2>DESCRIPTION</H2><PRE>
       Every  menu  has  an  associated pattern match buffer.  As
       input events that are printable characters come  in,  they
       are  appended to this match buffer and tested for a match,
       as described in <STRONG><A HREF="menu_driver.3x.html">menu_driver(3x)</A></STRONG>.

       The function <STRONG>set_menu_pattern</STRONG> 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  <STRONG>menu_pattern</STRONG>  returns the pattern buffer of
       the given <EM>menu</EM>.


</PRE>
<H2>RETURN VALUE</H2><PRE>
       The function <STRONG>menu_pattern</STRONG> returns a pointer, which is <STRONG>NULL</STRONG>
       if the <EM>menu</EM> parameter is <STRONG>NULL</STRONG>.  Otherwise, it is a pointer
       to a string which is empty if no pattern has been set.  It
       does not set errno.

       The  function  <STRONG>set_menu_pattern</STRONG>  may  return the following
       error codes:

       <STRONG>E_OK</STRONG> The routine succeeded.

       <STRONG>E_BAD_ARGUMENT</STRONG>
            Routine detected an incorrect or  out-of-range  argu-
            ment.

       <STRONG>E_BAD_STATE</STRONG>
            Routine was called from an initialization or termina-
            tion function.

       <STRONG>E_NOT_CONNECTED</STRONG>
            No items are connected to menu.

       <STRONG>E_NO_MATCH</STRONG>
            Character failed to match.

       <STRONG>E_SYSTEM_ERROR</STRONG>
            System error occurred (see <STRONG>errno</STRONG>).

<H2>PORTABILITY</H2><PRE>

       were not supported on Version 7 or BSD versions.
