Wireshark · Ethereal-dev: [Ethereal-dev] cinfo null when tree is not. How to update COL_INFO?

[Andy Howell <AndyHowell@xxxxxxxxxxxxx>]

Hello,

   In my dissector, I am trying to set COL_INFO using:

     if(tree)
           if (check_col(pinfo->cinfo, COL_INFO))
               col_set_str(pinfo->cinfo, COL_INFO, "This is my  message");

pinfo->cinfo is always null, so I can't set the column.
Do I need to save cinfo when the dissector is called with tree = NULL?

Thanks,

   Andy
