gboolean save_info; 
    
/* dont update the INFO or PROTOCOL fields of the summary */ 
           save_info=col_get_writable(pinfo->cinfo); 
           col_set_writable(pinfo->cinfo, FALSE); 

           :
           :

           col_set_writable(pinfo->cinfo, save_info); 

Then the sub´dissector cannot write anything, but if you want it to be able to add information but not clear the information already written then you can use col_set_fence.

	col_set_fence(pinfo->cinfo,COL_INFO);
