Yes, initscr() changes the screen and resets the cursor and stuff.

Maybe you should consider doing an ioctl yourself; that's what
initscr() does to get the size of the terminal:

at ncurses/tinfo/lib_setup.c:151:
ioctl(cur_term->Filedes, IOCTL_WINSIZE, &size)

Look for documentation about ioctl.

Also, FWIW, the ncurses source tarball comes with an Ada binding.
