Declaration [src]

g_permission_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.

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 method 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 acquired.
