Apparently, there is not consistency among different operating

|
|
566 |
systems on how to use FIONREAD.
|
|
|
567 |
|
|
|
568 |
FreeBSD, Linux and Solaris all expect the 3rd argument to
|
|
|
569 |
ioctl() to be an int, which is normally 32-bit even on 64-bit
|
|
|
570 |
machines.
|
|
|
571 |
|
|
|
572 |
IRIX, on the other hand, expects a size_t, which is 64-bit on
|
|
|
573 |
64-bit machines.
|
|
|
574 |
|
|
|
575 |
So, the solution is to use size_t initialized to zero to make
|
|
|
576 |
sure all bits are set to zero, preventing underflow with the
|
|
|
577 |
FreeBSD/Linux/Solaris ioctls.
