Combine them, or use the function that queries how much is available
(I forget the key name). In pseudo code:

   read(1);       // blocks & sleeps
   set_nonblock_mode();
   read(max);
   set_block_mode()

or

   read(1);    // blocks & sleeps
   how_much_available(&len);
   read(len)

I'm sure there are other ways as well.
