61        Every  menu  has  an  associated pattern match buffer.  As input events
62        that are printable characters come in, they are appended to this  match
63        buffer and tested for a match, as described in <STRONG><A HREF="menu_driver.3x.html">menu_driver(3x)</A></STRONG>.
64
65        The  function  <STRONG>set_menu_pattern</STRONG>  sets  the pattern buffer for the given
66        menu and tries to find the first matching item.  If it  succeeds,  that
67        item becomes current; if not, the current item does not change.
68
69        The function <STRONG>menu_pattern</STRONG> returns the pattern buffer of the given <EM>menu</EM>.

73        The  function <STRONG>menu_pattern</STRONG> returns a pointer, which is <STRONG>NULL</STRONG> if the <EM>menu</EM>
74        parameter is <STRONG>NULL</STRONG>.  Otherwise, it is a pointer to  a  string  which  is
75        empty if no pattern has been set.  It does not set <STRONG>errno</STRONG>.
76
77        The function <STRONG>set_menu_pattern</STRONG> may return the following error codes:
78
79        <STRONG>E_OK</STRONG> The routine succeeded.
80
81        <STRONG>E_BAD_ARGUMENT</STRONG>
82             Routine detected an incorrect or out-of-range argument.
83
84        <STRONG>E_BAD_STATE</STRONG>
85             Routine was called from an initialization or termination function.
86
87        <STRONG>E_NOT_CONNECTED</STRONG>
88             No items are connected to menu.
