Paul, I'd suggest the following (less functions and infinite
extensibility without any new functions):
typedef int (*LaagaCallback)(laaga_client_t *client, LaagaPropertyId);
/* To get callback arg */
void *laaga_get_property_custom(laaga_client_t *client,
LaagaPropertyId);
/* To get sample rate, buffer_size, etc. */
int laaga_get_value_integer(laaga_client_t *client, LaagaPropertyId);
int laaga_set_property_callback(laaga_client_t *client, LaagaPropertyId,
LaagaCallback);
int laaga_set_property_custom(laaga_client_t *client, LaagaPropertyId,
void *);
No other functions (do you want a simple client API, don't you?)
