<p><a class="link" href="gobject-Generic-values.html#GValue" title="GValue"><span class="type">GValue</span></a> 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 <a class="link" href="gobject-Type-Information.html#GType" title="GType"><span class="type">GType</span></a> with a
<a class="link" href="gobject-Type-Information.html#GTypeValueTable" title="struct GTypeValueTable"><span class="type">GTypeValueTable</span></a> in its <a class="link" href="gobject-Type-Information.html#GTypeInfo" title="struct GTypeInfo"><span class="type">GTypeInfo</span></a> structure. Parameter
specifications for most value types can be created as <a class="link" href="gobject-GParamSpec.html#GParamSpec" title="struct GParamSpec"><span class="type">GParamSpec</span></a>
derived instances, to implement e.g. <a class="link" href="gobject-The-Base-Object-Type.html#GObject"><span class="type">GObject</span></a> properties which
operate on <a class="link" href="gobject-Generic-values.html#GValue" title="GValue"><span class="type">GValue</span></a> containers.</p>
<p>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.</p>
