``void raw1394_set_userdata`(raw1394handle_t handle);`

## Arguments

  handle associated with the user data

## Description

Allows to associate one void pointer with a handle. libraw1394 does not care about the data, it just stores it in the handle allowing it to be retrieved at any time. This can be useful when multiple handles are used, so that callbacks can identify the handle.
