Virtual Method
GioPermissionacquire
since: 2.26
Declaration [src]
gboolean
acquire (
GPermission* permission,
GCancellable* cancellable,
GError** error
)
Description [src]
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.
