Great!

In my case the exported function can be invoked from any kind of
route, and I don't want PV's to be cleaned when entering in
branch_route so I expect that the callback should look as follows:

  register_script_cb( clean_pvs,
POST_SCRIPT_CB|REQUEST_CB|FAILURE_CB|ONREPLY_CB , 0 )

This is, I don't need to add BRANCH_CB or ONSEND_CB as I just want the
PV to be cleaned after terminating the request/response process.
branch_route and onsend_route run over the same process as
request_route (or failure_route) so I don't need to include them, am I
right?

Thanks a lot.
