◆ BOUNCE
| #define BOUNCE | ( | c, | |
| m | |||
| ) | embutil::bounce<c, decltype(&c::m), &c::m> |
Convenience macro to simplify bounce statement usage.
The BOUNCE() macro simplifies the creation of a bounce function to a class member for use with C-style callbacks. The BOUNCE() macro must be paried with a this pointer to get to the proper class instance.
Example usage with a C-style callback interface.
posixThread is a C++ class, and posixThread::thread_func() is a member function which we want to pass to pthread_create().
// Our interfaces demand a void(*)(void*), so we adapt to posix's requirement
// and simply skip out on the return to the caller's perspective
r = pthread_create(&handle_, &attributes,
reinterpret_cast<void*>(this));
- Parameters
-
c The class type. m The member function in the class
- Returns
- A bounce function which redirects a C-style callback to a class member function.
