### Method

# GUPnP Acl is_allowed_async

since: 0.20.11

#### Declaration [src]

    void
    gupnp_acl_is_allowed_async (
      GUPnPAcl* self,
      GUPnPDevice* device,
      GUPnPService* service,
      const char* path,
      const char* address,
      const char* agent,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

Check asynchronously whether an IP address is allowed to access this resource.

This function is optional. `gupnp_acl_can_sync()` should return `TRUE` if the implementing class supports it. If it is supported, GUPnP will prefer to use this function over `gupnp_acl_is_allowed()`.

Implement this function if the process of verifying the access right is expected to take some time, for example when using D-Bus etc.

Use `gupnp_acl_is_allowed_finish()` to retrieve the result.

Available since: 0.20.11

This method completes asynchronously. Use `gupnp_acl_is_allowed_finish()` inside the `GAsyncReadyCallback` to obtain the result of the operation.
