|
|
* UAT maintains a dynamically allocated table accessible to the user
|
|
* via a file and/or via GUI preference dialogs.
|
|
*
|
|
* The file is read from and written in the personal configuration directory. If
|
|
* there is no such file, defaults will be loaded from the global data
|
|
* directory.
|
|
*
|
|
* The behaviour of the table is controlled by a series of callbacks which
|
|
* the caller (e.g. a dissector) must provide.
|
|
*
|
|
* BEWARE that the user can change an UAT at (almost) any time (via the GUI).
|
|
* That is, pointers to records in an UAT are valid only during the call
|
|
* to the function that obtains them (do not store pointers to these records).
|
|
* The records contents are only guaranteed to be valid in the post_update_cb
|
|
* function. (Implementation detail: currently a race condition is possible
|
|
* where the UAT consumer (dissector code) tries to use the UAT while the GUI
|
|
* user frees a record resulting in use-after-free. This is not ideal and might
|
|
* be fixed later.)
|
|
*
|
|
* UATs are meant for short tables of user data (passwords and such), there is
|
|
* no quick access, you must iterate through them each time to fetch the record
|
|
* you are looking for.
|
|
*
|
|
* Only users via GUI or editing the file can add/remove records, your
|
|
* (dissector) code cannot.
