+  There are several ways, but none of them are instant. There is no function
+  you can call from another thread or similar that will stop it immediately.
+  Instead you need to make sure that one of the callbacks you use return an
+  appropriate value that will stop the transfer.
+

+  the read callback and the write callback.
+
+  If you're using the multi interface, you also stop a transfer by removing
+  the particular easy handle from the multi stack.
