ioctl command FIONREAD

[Bubulac Tatiana]

Hello,


Does anyone know what FIONREAD ioctl command does means? I use SCO Open
Server 5.05.
In Linux this command does not exist.

TIA

As Harvinder says, it reports the number of bytes available for
reading from a descriptor.

You have already got the answer. Just to add that FIONREAD applies only to
non-blocking I/O.

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
ioctl System Call   -> Page 323
