As input events that are printable characters come in, they are appended to this match buffer and tested for a match, as described in \fBmenu_driver\fR(3X). .PP The function \fBset_menu_pattern\fR 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. .PP The function \fBmenu_pattern\fR returns the pattern buffer of the given \fImenu\fR. .SH RETURN VALUE The function \fBmenu_pattern\fR returns a pointer, which is \fBNULL\fR if the \fImenu\fP parameter is \fBNULL\fP. Otherwise, it is a pointer to a string which is empty if no pattern has been set. It does not set errno. .PP The function \fBset_menu_pattern\fR may return the following error codes: .TP 5 .B E_OK The routine succeeded. .TP 5 .B E_BAD_ARGUMENT Routine detected an incorrect or out-of-range argument. .TP 5 .B E_BAD_STATE Routine was called from an initialization or termination function. .TP 5 .B E_NOT_CONNECTED No items are connected to menu. .TP 5 .B E_NO_MATCH Character failed to match. .TP 5 .B E_SYSTEM_ERROR System error occurred (see \fBerrno\fR(3)). .SH SEE ALSO \fBcurses\fR(3X), \fBmenu\fR(3X). .SH NOTES The header file \fB<menu.h>\fR automatically includes the header file \fB<curses.h>\fR. .SH PORTABILITY These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions. .SH AUTHORS Juergen Pfeifer. Manual pages and adaptation for new curses by Eric S. Raymond.
