The item leftmost on the given row +becomes current. The function \fBtop_row\fR returns the number of the top menu +row being displayed. + +The function \fBitem_index\fR returns the (zero-origin) index of \fIitem\fR in +the menu's item pointer list. +.SH RETURN VALUE +\fBcurrent_item\fR returns \fBNULL\fR on error. + +\fBtop_row\fR and \fBitem_index\fR return \fBERR\fR (the general \fBcurses\fB +error value) on error. + +\fBset_current_item\fR and \fBset_top_row\fR return one of the following: +.TP 5 +\fBE_OK\fR +The routine succeeded. +.TP 5 +\fBE_SYSTEM_ERROR\fR +System error occurred (see \fBerrno\fR). +.TP 5 +\fBE_BAD_ARGUMENT\fR +Routine detected an incorrect or out-of-range argument. +.TP 5 +\fBE_BAD_STATE\fR +Routine was called from an initialization or termination function. +.TP 5 +\fBE_NOT_CONNECTED\fR +No items are connected to the menu. +.SH SEE ALSO +\fBcurses\fR(3), \fBmenu\fR(3). +.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. + +The SVr4 menu library documentation specifies the \fBtop_row\fR and +\fBindex_item\fR error value as -1 (which is the value of \fBERR\fR). +.SH AUTHORS +Juergen Pfeifer.
