Hi,
As far as I know the intention is to "fence off" the previously built column and stop it from beeing manipulated by
subsequent dissectors, noting is prepended or appended you could view it as the subsequent dissector is
handled an empty column.
This means that you'd probably want to add a space to the text added before setting the fence.
Example from -h225.c
if (contains_faststart == TRUE )
{
if (check_col(pinfo->cinfo, COL_INFO))
{
col_append_str(pinfo->cinfo, COL_INFO, "OpenLogicalChannel " );
}
}
col_set_fence(pinfo->cinfo,COL_INFO);
Best regards
Anders

We're coming closer :-)
What will happen then?
If the text won't be overwriten with col_set_srt (and alike) will the
new column text be prepended or appended to the old? Is there a
delimiting character and if there is, which one?
