And what exactly does an IOCTL function do?

Generally it's a system API that makes a request to get or set some
specific information. Often this is associated with hardware or the
settings affecting some hardware. A request is associated to an open
file handle. So an open handle to a socket is needed for socket ioctl's
while an open handle to a terminal is needed for terminal ioctl's.
Ioctl's requests do not have any official standards and vary from system
to system, although there are many de facto requests found on most systems.
Ioctl calls are a method of getting or setting information when a specific
API call doesn't exist (or didn't at one point in time).

Why do you ask?
