Create a row type
To create a row type, you create a row structure (MI_ROW) that holds the row type.
The mi_row_create() function is the constructor
function for the row structure (MI_ROW). To create a row type with mi_row_create(),
you must provide the following information to the function:
- A row descriptor that describes the fields of the row type (or columns of a row)
- The values of the row-type fields (or row columns)
