Creates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.
If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
#GBinding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.

Increases the freeze count on object. If the freeze count is
non-zero, the emission of "notify" signals on object is
stopped. The signals are queued until the freeze count is decreased
to zero. Duplicate notifications are squashed so that at most one
#GObject::notify signal is emitted for each property modified while the
object is frozen.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

Searches for S/MIME certificates or PGP keys for the given recipients,
which are returned as base64 encoded strings in out_certificates.
This is used when encrypting messages. The flags influence what
the out_certificates will contain. The order of items in out_certificates
should match the order of items in recipients, with %NULL data for those
which could not be found.
The function should return failure only if some fatal error happened. It's not an error when certificates for some, or all, recipients could not be found.
This method is optional and the default implementation returns %TRUE
and sets the out_certificates to %NULL. It's the only exception
when the length of recipients and out_certificates can differ.
In all other cases the length of the two should match.
The out_certificates will be freed with g_slist_free_full (certificates, g_free);

Checks whether object has a [floating][floating-ref] reference.
Returns a list of all #CamelService objects previously added using camel_session_add_service().
The services returned in the list are referenced for thread-safety. They must each be unreferenced with g_object_unref() when finished with them. Free the returned list itself with g_list_free().
An easy way to free the list property in one step is as follows:

Looks up for the name in address books.

Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.
Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.
the name of a property installed on the class of object.
Emits a "notify" signal for the property specified by pspec on object.
This function omits the property name lookup, hence it is faster than g_object_notify().
One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:
enum
{
PROP_0,
PROP_FOO,
PROP_LAST
};
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
0, 100,
50,
G_PARAM_READWRITE);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:
g_object_notify_by_pspec (self, properties[PROP_FOO]);
the #GParamSpec of a property installed on the class of object.
Returns the #GMainContext on which event sources for session are to
be attached.
References a #GNetworkMonitor instance, which had been previously set by camel_session_set_network_monitor(). If none is set, then the default #GNetworkMonitor is returned, as provided by g_network_monitor_get_default(). The returned pointer is referenced for thread safety, unref it with g_object_unref() when no longer needed.
Looks up a #CamelService by its unique identifier string. The service must have been previously added using camel_session_add_service().

Increase the reference count of object, and possibly remove the
[floating][floating-ref] reference, if object has a floating reference.
In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.
Since GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().
Removes all #CamelService instances added by camel_session_add_service().
This can be useful during application shutdown to ensure all #CamelService instances are freed properly, especially since #CamelSession instances are prone to reference cycles.
Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
If the object already had an association with that name, the old association will be destroyed.
Internally, the key is converted to a #GQuark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the #GQuark storage growing unbounded.

This function gets back user data pointers stored via
g_object_set_qdata() and removes the data from object
without invoking its destroy() function (if any was
set).
Usually, calling this function is only required to update
user data pointers with a destroy notifier, for example:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().
A #GQuark, naming the user data pointer
This function provides a simple mechanism for providers to initiate low-priority background jobs. Jobs can be submitted from any thread, but execution of the jobs is always as follows:
The #CamelSession:job-started signal is emitted from the thread
in which session was created. This is typically the same thread
that hosts the global default #GMainContext, or "main" thread.
The callback function is invoked from a different thread where
it's safe to call synchronous functions.
Once callback has returned, the #CamelSesson:job-finished signal
is emitted from the same thread as #CamelSession:job-started was
emitted.
Finally if a notify function was provided, it is invoked and
passed user_data so that user_data can be freed.
human readable description of the job, shown to a user
a #CamelSessionCallback
Reverts the effect of a previous call to
g_object_freeze_notify(). The freeze count is decreased on object
and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.
Prompts the user whether to accept certificate for service. The
set of flags given in errors indicate why the certificate failed
validation.
If an error occurs during prompting or if the user declines to respond, the function returns #CAMEL_CERT_TRUST_UNKNOWN and the certificate will be rejected.

Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.
Emits a #CamelSession:user_alert signal from an idle source on the main loop. The idle source's priority is #G_PRIORITY_LOW.
The purpose of the signal is to propagate a server-issued alert message
from service to a user interface. The type hints at the nature of the
alert message.

This function essentially limits the life time of the closure to
the life time of the object. That is, when the object is finalized,
the closure is invalidated by calling g_closure_invalidate() on
it, in order to prevent invocations of the closure with a finalized
(nonexisting) object. Also, g_object_ref() and g_object_unref() are
added as marshal guards to the closure, to ensure that an extra
reference count is held on object during invocation of the
closure. Usually, this function will be called on closures that
use this object as closure data.

name of a property to look up.
Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.
This function is meant to be called from the interface's default
vtable initialization function (the class_init member of
#GTypeInfo.) It must not be called after after class_init has
been called for any object types implementing this interface.
