PolkitSubject is implemented by PolkitSystemBusName, PolkitUnixProcess and PolkitUnixSession.
guint
polkit_subject_hash (PolkitSubject *subject
);
Gets a hash code for subject
that can be used with e.g. g_hash_table_new()
.
gboolean polkit_subject_equal (PolkitSubject *a
,PolkitSubject *b
);
Checks if a
and b
are equal, ie. represent the same subject.
This function can be used in e.g. g_hash_table_new()
.
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
from. You can then call polkit_subject_exists_finish()
to get the
result of the operation.
gboolean polkit_subject_exists_finish (PolkitSubject *subject
,GAsyncResult *res
,GError **error
);
Finishes checking whether a subject exists.

res |
A GAsyncResult obtained from the GAsyncReadyCallback passed to |

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.
gchar *
polkit_subject_to_string (PolkitSubject *subject
);
Serializes subject
to a string that can be used in
polkit_subject_from_string()
.
PolkitSubject * polkit_subject_from_string (const gchar *str
,GError **error
);
Creates an object from str
that implements the PolkitSubject
interface.

A string obtained from |

typedef struct _PolkitSubject PolkitSubject;
Generic type for all objects that can be used as subjects.
