Set an atomic variable to a new value if it is currently an old value.
Note: If you don't know what this function is for, you shouldn't use it!
\param a a pointer to an SDL_atomic_t variable to be modified \param oldval the old value \param newval the new value \returns SDL_TRUE if the atomic variable was set, SDL_FALSE otherwise.
\since This function is available since SDL 2.0.0.
