Description
esp_err_t (*)(size_t props_count,
const esp_local_ctrl_prop_t props[],
esp_local_ctrl_prop_val_t prop_values[],
void *usr_ctx)
Handler function to be implemented for retrieving current values of properties.
esp_err_t (*)(size_t props_count,
const esp_local_ctrl_prop_t props[],
const esp_local_ctrl_prop_val_t prop_values[],
void *usr_ctx)
Handler function to be implemented for changing values of properties.
void *
Context pointer to be passed to above handler functions upon invocation. This is different from the property level context, as this is valid throughout the lifetime of the `esp_local_ctrl` service, and freed only when the service is stopped.
void (*)(void *usr_ctx)
Pointer to function which will be internally invoked on `usr_ctx` for freeing the context resources when `esp_local_ctrl_stop()` is called.
