Plugin IF enhances the capabilities of the plugin framework to provide
functions such as Go To Frame and Apply Display Filter. The Plugin IF
functions don't provide any form of feedback; there is no values returned.
During the development of a plugin I found a significant hindrance was the lack
of status information, particularly pertaining to the loaded capture file and
the current position within it. Of particular concern is lack of visibility of
the current frame number.
Unfortunately, the frame number handed to the dissector via the pinfo structure
(pinfo->fd->num) does not always indicate the display position within the
capture file, for example during scanning and after a filter has been applied.
I have written a simple one-function extension to Plugin IF with the following
interface:
typedef struct _cf_info_t cf_info_t;
struct _cf_info_t
{
file_state state; /* Current state of capture file */
gchar * filename; /* Name of capture file */
guint32 count; /* Total number of frames */
guint32 framenr; /**< Currently displayed frame number */
unsigned int passed_dfilter; /**< 1 = display, 0 = no display */
};
WS_DLL_PUBLIC void plugin_if_get_cf_status(cf_info_t * status_info);
It requires no changes to existing code by simply building on what already
exists.
I'm not sure how I'm supposed to handle this but I'll submit the code via
gerrit and see if it's accepted.
