Set the outside file of decoding from GUI configuration

I wrote a plugin for my protocol whose decoding depends on a file passed to it from the outside. Can I get that file can be properly set by acting directly on the properties of the plugin from the GUI of Wireshark?

Thank you in advance.

I'm assuming here that you want to set the pathname of the file from the GUI.

If so, you want to register a "filename" preference, which is a string preference that also supports a "Browse" button, allowing the user to browse the file system through the GUI. See, for example, epan/dissectors/packet-kerberos.c, which registers a "filename" preference using prefs_register_filename_preference().

Two questions:

Is the correct call every time the function of reading the string from the preferences by entering the function call in "dissect_myProto" or is there a way to invoke it only when the preference is changed?

How do I delete the preference, and then deallocate the string corresponding to the fie, when I close my wireshark?
