Overview
This function shall iterate the underlying cursor, setting bson to the next document.
This function is a blocking function.
Returns
This function returns true if a valid bson document was read from the cursor. Otherwise, false if there was an error or the cursor was exhausted.
Errors can be determined with the mongoc_cursor_error() function.
Lifecycle
The bson objects set in this function are ephemeral and good until the next call. This means that you must copy the returned bson if you wish to retain it beyond the lifetime of a single call to mongoc_cursor_next().
