Virtual Method


since: 2.26


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


Attempts to release the permission represented by permission.

The precise method by which this happens depends on the permission and the underlying authentication mechanism. In most cases the permission will be dropped immediately without further action.

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

If the permission is released 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_release_async() for the non-blocking version.

Available since: 2.26



Type: GCancellable

A GCancellable, or NULL.

The argument can be NULL.
The data is owned by the caller of the function.

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will left initialized to NULL by the virtual function if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

TRUE if the permission was successfully released.
