Classes
struct	osvr::util::this_last_t
	Tag type indicating the last parameter of the function contains the "this" pointer. More...
struct	osvr::util::this_first_t
	Tag type indicating the first parameter of the function contains the "this" pointer. More...
struct	osvr::util::GenericCaller< FunctionPtr, FunctionObjectType, ThisLocation >
	Struct containing a single static function member named "call" that serves as a converter from a function call with an opaque userdata pointer to a functor call using the userdata pointer as "this". More...

Namespaces
	osvr
	The main namespace for all C++ elements of the framework, internal and external.
	osvr::util
	The Util library: Functionality not necessarily coupled to any particular core library, serving more as a common base layer behind all systems.

Functions
template<typename FunctionPtr , typename FunctionObjectType , typename ThisLocation >
FunctionPtr	osvr::util::getCaller ()
	Get a generic functor caller: a pointer to a function that will call an object of your specific function object type, expecting the function object address passed as a void * as a parameter. More...
template<typename FunctionPtr , typename FunctionObjectType , typename ThisLocation >
FunctionPtr	osvr::util::getCaller (ThisLocation const &)
	Get a generic functor caller. Specify the location of "this" through the argument: results in automatic type deduction for ThisLocation. More...
template<typename FunctionPtr , typename FunctionObjectType , typename ThisLocation >
FunctionPtr	osvr::util::getCaller (FunctionObjectType const *, ThisLocation const &)
	Get a generic functor caller. Pass a pointer to a function object and specify the location of "this" through the argument: results in automatic type deduction for FunctionObjectType and ThisLocation. More...

Variables
BOOST_CONSTEXPR_OR_CONST this_last_t	this_last = {}
	Pass as an argument to a getCaller() overload to indicate the last parameter of the function contains the "this" pointer. More...
BOOST_CONSTEXPR_OR_CONST this_first_t	this_first = {}
	Pass as an argument to a getCaller() overload to indicate the first parameter of the function contains the "this" pointer. More...
