Gio.Permission.release
Description: Reference for Gio.Permission.release

### Virtual Method

# Gio Permissionrelease

since: 2.26

#### Declaration [src]

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

#### Description [src]

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

#### Parameters

`cancellable`

  Type: `GCancellable`

  A `GCancellable`, or `NULL`.

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

`error`

  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 be 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.
