  60 GITypeInfo represents a type. You can retrieve a type info from
  61 an argument (see <a class="link" href="gi-GIArgInfo.html#GIArgInfo" title="GIArgInfo"><span class="type">GIArgInfo</span></a>), a functions return value (see <a class="link" href="gi-GIFunctionInfo.html#GIFunctionInfo" title="GIFunctionInfo"><span class="type">GIFunctionInfo</span></a>),
  62 a field (see <a class="link" href="gi-GIFieldInfo.html#GIFieldInfo" title="GIFieldInfo"><span class="type">GIFieldInfo</span></a>), a property (see <a class="link" href="gi-GIPropertyInfo.html#GIPropertyInfo" title="GIPropertyInfo"><span class="type">GIPropertyInfo</span></a>), a constant
  63 (see <a class="link" href="gi-GIConstantInfo.html#GIConstantInfo" title="GIConstantInfo"><span class="type">GIConstantInfo</span></a>) or for a union discriminator (see <a class="link" href="gi-GIUnionInfo.html#GIUnionInfo" title="GIUnionInfo"><span class="type">GIUnionInfo</span></a>).
  64 </p>
  65 <p>
  66 A type can either be a of a basic type which is a standard C primitive
  67 type or an interface type. For interface types you need to call
  68 <a class="link" href="gi-GITypeInfo.html#g-type-info-get-interface" title="g_type_info_get_interface ()"><code class="function">g_type_info_get_interface()</code></a> to get a reference to the base info for that
  69 interface.
