You can't read from the stderr stream which the `dialog' command uses;
it is your process' stderr stream. You could add e.g. ` 2>dialog.out'
to the end of the string which is passed to system. This would write
the result to the file `dialog.out', which you could then read.
If you want to get the stderr output of a command, you would need to
implement something similar to popen(), but which reads from stderr
instead of stdout.

Is unctrl.h in the /usr/include/ncurses directory? It should be in
/usr/include, along with ncurses.h.

This is the same problem as before.
