Dbc::del

						#include <db_cxx.h>
						int
						Dbc::del(u_int32_t flags);
					

Description

The Dbc::del method deletes the key/data pair currently referenced by the cursor.

The flags parameter is currently unused, and must be set to 0.

The cursor position is unchanged after a delete, and subsequent calls to cursor functions expecting the cursor to reference an existing key will fail.

If the element has already been deleted, Dbc::del will return DB_KEYEMPTY.

If the cursor is not yet initialized, the Dbc::del method either returns EINVAL or throws an exception that encapsulates EINVAL.

Otherwise, the Dbc::del method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.
