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>.
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.
69 The function <STRONG>menu_pattern</STRONG> returns the pattern buffer of the given <EM>menu</EM>.
72 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
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>.
77 The function <STRONG>set_menu_pattern</STRONG> may return the following error codes:
79 <STRONG>E_OK</STRONG> The routine succeeded.
81 <STRONG>E_BAD_ARGUMENT</STRONG>
82 Routine detected an incorrect or out-of-range argument.
84 <STRONG>E_BAD_STATE</STRONG>
85 Routine was called from an initialization or termination function.
87 <STRONG>E_NOT_CONNECTED</STRONG>
88 No items are connected to menu.
90 <STRONG>E_NO_MATCH</STRONG>
91 Character failed to match.
93 <STRONG>E_SYSTEM_ERROR</STRONG>
94 System error occurred (see <STRONG>errno(3)</STRONG>).
