Hy,

Yep I think it is a regular way of using them.
To read back your data you can do it like that :

g_list_foreach(BigGList, ReadRow);


And then you declare a function which has this prototype :
void ReadRow(gpointer pxData_I)
{
    GList    *paBigList = (GList *)pxData_I;
    GList    *paRowList = NULL;
    gpointer    pxInfoCell = NULL;

    /* paBigList points on one of the element of your list */
    /* So we just have to retrieve the GList contained into this element */
    paRowList = (GList *)paBigList->data;

    /* Now if you want to read one element of your GList, you do it like
that : */
    pxInfoCell = (g_list_nth(paRowList, 4))->data;

    /* Or if you want to read the whole row */
    g_list_foreach(paRowList, ReadCell);
    /* Where RowCell is a function of this form : void ReadCell(gpointer
pxData_I); */
}
