I am working on an application that takes use of boost::thread. During the
initial method of my application I need to pass one argument to the method.
As per the api documentation for boost::thread I am using the following:
boost::thread dataThread(dparse.dataMain,instUUID);
dataThread.join();
However, when I attempt to use this, I get the following exception from my
compiler. Is there something that I am missing? I do not see how my thread
constructor is any different from the constructor in the api documentation.
Any help with this is greatly appreciated.

You'll need to use Boost.Bind.
