+** If one or more of the SQL statements are queries, then

+** The 4th parameter is an arbitrary pointer that is passed

+**
+** The 2nd parameter to the callback function is the number of

+** of string holding the values for each column. The 4th parameter
+** is an array of strings holding the names of each column.
+**
+** The callback function may be NULL, even for queries. A NULL
+** callback is not an error. It just means that no callback
+** will be invoked.
+**
+** If an error occurs while parsing or evaluating the SQL (but
+** not while executing the callback) then an appropriate error
+** message is written into memory obtained from malloc() and
+** *errmsg is made to point to that message. If errmsg==NULL,
+** then no error message is ever written. The return value is
