Detailed Description

template<typename T>
class vsmc::DispatchFunction< T >

Wrap a callable object into a dispatch_function_t type pointer.

It is important that this object live at least after the completion of the work. This is a thin wrapper around a regular C++ callable object (including lambda expressions) that make it easier to interface them with GCD. The memory management issue is the same as using raw GCD interface with a context variable, which shall not be destroyed before the execution of the function finishes. The original object does not need to exist after the creation of DispatchFunction.
