I am writing a dissector for a custom protocol and found that I am unable to add additional information to the INFO column. See the following code:
if (check_col(pinfo->cinfo, COL_INFO)) {
col_append_str(pinfo->cinfo, COL_INFO, " more info");
}
It appears that after the initial setting of the column, pinfo->cinfo is no longer writable. That is
col_get_writable(pinfo->cinfo)
always returns false. It still returns false even after I run:
col_set_writable(pinfo->cinfo, 1);
Has anyone else run across this? I thought I had this working for another dissector on 0.99.6 but I don't have that code with me right now.
Thanks for any thoughts, comments, ideas -- Jason
