      GCancellable* cancellable,

    )

#### Description [src]

This is a wrapper of e_cache_get_offline_state(), ensuring that a correct `ECache` UID will be used.

Available since: 3.34

#### Parameters

`uid`

  Type: `const gchar*`

  A UID of the component.

  The data is owned by the caller of the method.
  The value is a NUL terminated UTF-8 string.

  Type: `const gchar*`

  An optional Recurrence-ID.

  The argument can be `NULL`.

`error`

  Type: `GError **`

  The return location for a recoverable error.
