Detailed Description

This set of functions provide column-wise accesses to query results.

Return a pointer to an array holding the values of attribute att that qualifies the specified selection conditions.

Note

The caller can NOT free the memory pointed by the pointer returned. Must call fastbit_destroy_query to free the memory after use. This applies to all other versions of fastbit_get_qualified_ttt.
