MI_TYPEID *mi_column_type_id(rdesc, column_no)

		MI_ROW_DESC *rdesc;

		mi_integer column_no; 


rdesc
is a pointer to the row descriptor of the row that contains the column. A  row descriptor describes the structure of a row or composite value. Call mi_get_row_desc() or mi_get_row_desc_without_row() to obtain it.

column_no
indicates the position of the column in the specified row descriptor. Column numbering follows C programming conventions, so the first column in the row is at position zero.
