-      Apparently, there is not consistency among different operating
-      systems on how to use FIONREAD.
-
-      FreeBSD, Linux and Solaris all expect the 3rd argument to
-      ioctl() to be an int, which is normally 32-bit even on 64-bit
-      machines.
-
-      IRIX, on the other hand, expects a size_t, which is 64-bit on
-      64-bit machines.
-
-      So, the solution is to use size_t initialized to zero to make
-      sure all bits are set to zero, preventing underflow with the
-      FreeBSD/Linux/Solaris ioctls.
