Fetch an element

You fetch an element from an open collection with the mi_collection_fetch() function. You can perform a fetch operation on a read/write or a read-only cursor.

To fetch a collection element, you must specify:

The connection with which the collection is associated
The collection descriptor for the collection from which you want to fetch elements
The location of the cursor position at which to begin the fetch
A variable that holds a single fetched element and one that holds its length
