Set error status on cloud file

Question

When working with the Cloud Filter API and using CfSetPinState API, it does not provide error status.
typedef enum CF_PIN_STATE {
CF_PIN_STATE_UNSPECIFIED,
CF_PIN_STATE_PINNED,
CF_PIN_STATE_UNPINNED,
CF_PIN_STATE_EXCLUDED,
CF_PIN_STATE_INHERIT
} ;

How to set error status like onedrive??
