The function \fBpost_menu\fR displays a menu to its associated subwindow. To
trigger physical display of the subwindow, use \fBrefresh\fR or some equivalent

input request will do).
The function \fBunpost_menu\fR erases menu from its associated subwindow.
.SH RETURN VALUE

.TP 5
\fBE_OK\fR
The routine succeeded.
.TP 5
\fBE_SYSTEM_ERROR\fR
System error occurred (see \fBerrno\fR).

\fBE_BAD_ARGUMENT\fR
Routine detected an incorrect or out-of-range argument.
.TP 5
\fBE_POSTED\fR
The menu has already been posted.
.TP 5
\fBE_BAD_STATE\fR

The menu has not been posted.
.TP 5
\fBE_NOT_CONNECTED\fR

.SH SEE ALSO
\fBcurses\fR(3X), \fBmenu\fR(3X).
.SH NOTES

\fB<curses.h>\fR.
.SH PORTABILITY
These routines emulate the System V menu library. They were not supported on
Version 7 or BSD versions.
