#define QB_HDB_X_FORMAT '%'PRIx64¶

typedef uint64_t qb_handle_t¶

Generic handle type is 64 bits.

uint32_t qb_hdb_base_convert (qb_handle_t handle)¶

void qb_hdb_create (struct qb_hdb * hdb)¶

Create a new database. Parameters:

void qb_hdb_destroy (struct qb_hdb * hdb)¶

Destroy a handle database. Parameters:

int32_t qb_hdb_handle_create (struct qb_hdb * hdb, int32_t instance_size, qb_handle_t * handle_id_out)¶

Create a new handle. Parameters:

Returns:

int32_t qb_hdb_handle_destroy (struct qb_hdb * hdb, qb_handle_t handle_in)¶

Request the destruction of the object. When the refcount is 0, it will be destroyed.

Parameters:

Returns:

int32_t qb_hdb_handle_get (struct qb_hdb * hdb, qb_handle_t handle_in, void ** instance)¶

Get the instance associated with this handle and increase it's refcount. Parameters:

Returns:

Get the current refcount. Parameters:

Returns:

int32_t qb_hdb_iterator_next (struct qb_hdb * hdb, void ** instance, qb_handle_t * handle)¶

Get the next object and increament it's refcount. Remember to call qb_hdb_handle_put()
