Virtual Method

GioPermissionacquire

Declaration

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

Description

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.

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 function.

error

Type: GError **

The return location for an error.

The argument can be NULL.

The argument will be set to NULL by the function if there are no errors.

In case of error, the argument will be set and the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

TRUE if the permission was successfully acquired.
