tcgetattr(3) to fetch the previous terminal attributes.
tcsetattr(3) to clear the ICANON, ISIG and ECHO bits and set the VMIN
and VTIME and to restore the previous settings afterwards.
write(1, "\033[6n", 4); to send the escape sequence.
read(0, &c, 1); to read characters one at a time until you find
'R'
sscanf to extract the coordinates from \e[y;xR string.

But it looks like what you really want is to use ncurses that
provides with all the functions to create visual applications on
a terminal.
