GValue provides an abstract container structure which can be copied, transformed and compared while holding a value of any (derived) type, which is registered as a GType with a GTypeValueTable in its GTypeInfo structure. Parameter specifications for most value types can be created as GParamSpec derived instances, to implement e.g. GObject properties which operate on GValue containers.
Parameter names need to start with a letter (a-z or A-Z). Subsequent characters can be letters, numbers or a '-'. All other characters are replaced by a '-' during construction.

void g_value_set_object (GValue *value, gpointer v_object);
Set the contents of a G_TYPE_OBJECT
derived GValue to v_object
.
g_value_set_object()
increases the reference count of v_object
(the GValue holds a reference to v_object
).
If you do not wish to increase the reference count of the object
(i.e. you wish to pass your current reference to the GValue because you no
longer need it),
use g_value_take_object()
instead.
It is important that your GValue holds a reference to v_object
(either its
own, or one it has taken) to ensure that the object won't be destroyed while
the GValue still exists).

void g_value_take_object (GValue *value, gpointer v_object);
Sets the contents of a G_TYPE_OBJECT
derived GValue to v_object
and takes over the ownership of the callers reference to v_object
;
the caller doesn't have to unref it any more (i.e. the reference
count of the object is not increased).
If you want the GValue to hold its own reference to v_object
, use
g_value_set_object()
instead.

void g_value_set_object_take_ownership (GValue *value, gpointer v_object);
g_value_set_object_take_ownership
has been deprecated since version 2.4 and should not be used in newly-written code. Use g_value_take_object()
instead.
This is an internal function introduced mainly for C marshallers.

Creates a new GParamSpecValueArray instance specifying a
G_TYPE_VALUE_ARRAY
property. G_TYPE_VALUE_ARRAY
is a G_TYPE_BOXED

with g_value_set_boxed()

Since 2.4
typedef struct { } GParamSpecOverride;
This is a type of GParamSpec type that simply redirects operations to
another paramspec. All operations other than getting or
setting the value are redirected, including accessing the nick and
blurb, validating a value, and so forth. See
g_param_spec_get_redirect_target()
for retrieving the overidden
property. GParamSpecOverride is used in implementing
g_object_class_override_property()
, and will not be directly useful
unless you are implementing a new base type similar to GObject.

GParamSpec* g_param_spec_override (const gchar *name, GParamSpec *overridden);
Creates a new property of type GParamSpecOverride. This is used to direct operations to another paramspec, and will not be directly useful unless you are implementing a new base type similar to GObject.
