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.
