+ * \fn const PHYSFS_Allocator *PHYSFS_getAllocator(void)
+ * \brief Discover the current allocator.
+ *
+ * (This is for limited, hardcore use. If you don't immediately see a need
+ *  for it, you can probably ignore this forever.)
+ *
+ * This function exposes the function pointers that make up the currently-used
+ *  allocator. This can be useful for apps that want to access PhysicsFS's
+ *  internal, default allocation routines, as well as for external code that
+ *  wants to share the same allocator, even if the application specified their
+ *  own.
+ *
+ * This call is only valid between PHYSFS_init() and PHYSFS_deinit() calls;
+ *  it will return NULL if the library isn't initialized. As we can't
+ *  guarantee the state of the internal allocators unless the library is
+ *  initialized, you shouldn't use any allocator returned here after a call
+ *  to PHYSFS_deinit().
+ *
+ * Do not call the returned allocator's Init() or Deinit() methods under any
+ *  circumstances.
+ *
+ * If you aren't immediately sure what to do with this function, you can
+ *  safely ignore it altogether.
+ *
+ *  \return Current allocator, as set by PHYSFS_setAllocator(), or PhysicsFS's
+ *          internal, default allocator if no application-defined allocator
+ *          is currently set. Will return NULL if the library is not
+ *          initialized.
