Type Alias b2EnqueueTaskCallback 

pub type b2EnqueueTaskCallback = Option<unsafe extern "C" fn(task: b2TaskCallback, taskContext: *mut c_void, userContext: *mut c_void) -> *mut c_void>;

These functions can be provided to Box2D to invoke a task system. Returns a pointer to the user’s task object. May be nullptr. A nullptr indicates to Box2D that the work was executed serially within the callback and there is no need to call b2FinishTaskCallback. @ingroup world
