Thanks Pascal – I always wondered when code appeared in a release.

There’s an enhancement to plugin_if that doesn’t address your needs directly but may give you enough functionality.  
It’s a function called plugin_if_get_ws_info.  You can call it from within a dissector and it populates the following 
structure:

typedef struct _ws_info_t
{
    gboolean ws_info_supported;                 /* false if no libpcap */
    file_state cf_state;                        /* Current state of capture file */
    gchar *cf_filename;                         /* Name of capture file */
    guint32 cf_count;                           /* Total number of frames */
    guint32 cf_framenr;                         /**< Currently displayed frame number */
    gboolean frame_passed_dfilter;              /**< true = display, false = no display */
} ws_info_t;

You may be able to interpret the cf_filename and cf_state values to give you what you need.

The plugin_if_get_ws_info code has been accepted and merged but it’s not in 2.0.1.  It’s in the latest git pull and I 
guess will be in 2.0.2.

No it will not be part of Wireshark 2.0.2 as it was not merged in the stable tree (only bugfixes are merged in the 
stable branch).
It is part of Wireshark 2.1.0 development tree that will become at some point Wireshark 2.2.0 stable release.
Best regards,
Pascal.
