Perhaps someone knows any workaround for what I am trying to do in my code 
or a way to implement this differently?

The code does the following:

//create a target list with text and HTML formats
GtkTargetList *list = gtk_target_list_new (NULL, 0);
gtk_target_list_add(list, atomTextHtml, 0, 0);
gtk_target_list_add_text_targets(list, 0);

//now I need to convert the target list to an array of the GtkTargetEntry 
structures as needed by gtk_clipboard_set_with_data
int nTargetCnt = g_list_length (list->list);
GtkTargetEntry *targets = g_new0 (GtkTargetEntry, nTargetCnt);
int i=0;
for (GList *l=list->list; l; l=l->next, i++)
{
GtkTargetPair *pair = (GtkTargetPair *)l->data;
targets[i].target = gdk_atom_name (pair->target);
}

//set the clipboard with target formats
gboolean bOK = gtk_clipboard_set_with_data(clipboard, targets, nTargetCnt, 
MyGtkClipboardGetFunc, NULL, 0);

Basically the big problem is that gtk_clipboard_set_with_data API does not 
use GtktargetList directly.
