can't print string pointer, get error?

["Carl B. Constantine" <duckwing duckwing ca>]

I have the following defined in my program:

gchar   *id;

I perform the following operation which fills id with appropriate
values:

gtk_tree_model_get(theModel, &custListIter, CUST_ID, &id, -1);

Then, I print out the value of id for debugging purposes:

g_printf("row number %s was retrieved\n", id);

but, upon compile, I receive the following error:

  callbacks.c:509: warning: char format, different type arg(arg 2)


Say what? Why am I getting this error? It doesn't make sense. You print
out string pointers using printf("%s", var) which works fine numer
normal C conditions. So why do I get this warning, and how do I fix it?

Thanks.
