/**
* @file
* @brief Information required to use the StreamingClient as a plugin.
*
* Sometimes it's useful for client applications to avoid linking against
* libola, say for instance if they install separately from OLA. By deferring
* the linking and using libola as a plugin, clients can use OLA if it's
* installed on the system or if not, take some other action like displaing a
* message or using another output mechanism.
*
* This file provides plugin interfaces so that a client code can load
* a small subset of libola at runtime. For each function we \#define the symbol
* name and then provide the function type signature and the actual function
* itself.
*
* http://www.tldp.org/HOWTO/html_single/C++-dlopen provides some good
* background.
