polkit_subject_hash ()

guint
polkit_subject_hash (PolkitSubject *subject);

Gets a hash code for subject that can be used with e.g. g_hash_table_new().

polkit_subject_equal ()

gboolean
polkit_subject_equal (PolkitSubject *a,
                      PolkitSubject *b);

Checks if a and b are equal, ie. represent the same subject. However, avoid calling polkit_subject_equal() to compare two processes; for more information see the PolkitUnixProcess documentation.

This function can be used in e.g. g_hash_table_new().

polkit_subject_exists ()

void
polkit_subject_exists (PolkitSubject *subject,
                       GCancellable *cancellable,
                       GAsyncReadyCallback callback,
                       gpointer user_data);

Asynchronously checks if subject exists.

When the operation is finished, callback will be invoked in the

thread-default main loop of the thread you are calling this method

from. You can then call polkit_subject_exists_finish() to get the result of the operation.

polkit_subject_exists_finish ()

gboolean
polkit_subject_exists_finish (PolkitSubject *subject,
                              GAsyncResult *res,
                              GError **error);

Finishes checking whether a subject exists.

polkit_subject_exists_sync ()

gboolean
polkit_subject_exists_sync (PolkitSubject *subject,
                            GCancellable *cancellable,
                            GError **error);

Checks if subject exists.

This is a synchronous blocking call - the calling thread is blocked until a reply is received. See polkit_subject_exists() for the asynchronous version.

polkit_subject_to_string ()

gchar *
polkit_subject_to_string (PolkitSubject *subject);

Serializes subject to a string that can be used in polkit_subject_from_string().

polkit_subject_from_string ()

PolkitSubject *
polkit_subject_from_string (const gchar *str,
                            GError **error);

Creates an object from str that implements the PolkitSubject interface.

PolkitSubject

typedef struct _PolkitSubject PolkitSubject;

Generic type for all objects that can be used as subjects.

struct PolkitSubjectIface

struct PolkitSubjectIface {
  GTypeInterface parent_iface;

  guint    (*hash)          (PolkitSubject       *subject);

  gboolean (*equal)         (PolkitSubject       *a,
                             PolkitSubject       *b);

  gchar *  (*to_string)     (PolkitSubject       *subject);

  void     (*exists)        (PolkitSubject       *subject,
                             GCancellable        *cancellable,
                             GAsyncReadyCallback  callback,
                             gpointer             user_data);

  gboolean (*exists_finish) (PolkitSubject       *subject,
                             GAsyncResult        *res,
                             GError             **error);

  gboolean (*exists_sync)   (PolkitSubject       *subject,
                             GCancellable        *cancellable,
                             GError             **error);
};

An interface for subjects.
