#include "btree.h"
int btdups(BTA* btact, int dups);
The btdups controls support for duplicate
keys in the current root of the index file associated with
the btact context pointer. Setting the
value of the dups to non-zero (TRUE)
will enable support for duplicate keys in the current root. A
value of zero (FALSE) will disable duplicate key support for
the current root. Enabling duplicate key support on the
superroot is not permitted.
Disabling duplicate key support on a root that previously permitted them merely prevents further duplicate keys from being inserted into the root BTree index. Existing duplicates will remain and must be managed by the application.
A non-zero return code indicates an error occurred.
