The function header is this:

   int readattr(void)

That tells you what data type the function returns.

Any way you want.  Declare a variable and assign it the result of the
function call.  After that do whatever you will with it.

Anyone who is doing low level video interrupt function calls should already
be long past the point of needing to learn how to write to the screen.
