Virtual Method



acquire (
  GPermission* permission,
  GCancellable* cancellable,
  GError** error


Attempts to acquire the permission represented by permission.

The precise method by which this happens depends on the permission and the underlying authentication mechanism. A simple example is that a dialog may appear asking the user to enter their password.

You should check with g_permission_get_can_acquire() before calling this function.

If the permission is acquired then TRUE is returned. Otherwise, FALSE is returned and error is set appropriately.

This call is blocking, likely for a very long time (in the case that user interaction is required). See g_permission_acquire_async() for the non-blocking version.
