Hello,
Does anyone know what FIONREAD ioctl command does means? I use SCO Open

In Linux this command does not exist.
TIA

FIONREAD returns in arg the number of bytes available to read from the file
descriptor.
for further refrence and how to use it you can check the book
Unix for Network Programming By Richard Stevens

As Harvinder says, it reports the number of bytes available for
