Dear All,

Is there a way to store a string in a temporary tvb buffer and then in
the dissection logic use this tvb buffer in the in order to read this
temporary string using function proto_tree_add_item and assign it to one
of the filter fields.
Sure, use tvb_new_real_data() to create a TVB which points to some memory. Do be aware that the memory has to stick around for a while so you may also need to use tvb_set_free_cb() so you can know when to free it.
