What exactly do you means by device callback event?

i want to send the event of the mouse to the server..

void Mouse3D::deviceValueCallback( void * inContext, IOReturn inResult, void * inSender, IOHIDValueRef inIOHIDValueRef )
{
//#pragma unused( inSender )
IOHIDElementRef eref = IOHIDValueGetElement( inIOHIDValueRef );
if (!eref) return;

IOHIDDeviceRef tIOHIDDeviceRef = IOHIDElementGetDevice(eref);
if (!tIOHIDDeviceRef) return;

Mouse3D *d = ( Mouse3D* ) inContext;
if (!d) return;

std::cout << std::endl;

UInt32 usagePage = IOHIDElementGetUsagePage( eref );
UInt32 usage = IOHIDElementGetUsage( eref );

if ( !usagePage || !usage ) return;
if ( -1 == usage ) return;

//HIDDumpElementInfo(eref);
CFIndex value = IOHIDValueGetIntegerValue(inIOHIDValueRef);

switch(usagePage)
{
case Usage::PRIMARY_USAGE_PAGE:
switch(usage)
{
case Usage::USAGE_X: d->asyncEvent.tx = value; break;
case Usage::USAGE_Y: d->asyncEvent.ty = value; break;
case Usage::USAGE_Z: d->asyncEvent.tz = value; break;
case Usage::USAGE_RX: d->asyncEvent.rx = value; break;
case Usage::USAGE_RY: d->asyncEvent.ry = value; break;
case Usage::USAGE_RZ: d->asyncEvent.rz = value; break;
}
break;

case Usage::USAGE_PAGE_BUTTON:
d->asyncEvent.buttons[usage-1] = (value == 1); break;
break;
}

d->asyncEvent.printOn(std::cout);

}
}
this is the device value call back

You need a client, a counter part which communicates to your networking class CFTcpServer. For example create a client socket that connects to you server (port 8000 in your example), then for each mouse event collect the relevant information and send it to the server. Start with a simple networking example.
