g_variant_builder_init (
  GVariantBuilder* builder,
  const GVariantType* type


Initialises a GVariantBuilder structure.

type must be non-NULL. It specifies the type of container to construct. It can be an indefinite type such as G_VARIANT_TYPE_ARRAY or a definite type such as “as” or “(ii)”. Maybe, array, tuple, dictionary entry and variant-typed values may be constructed.

After the builder is initialised, values are added using g_variant_builder_add_value() or g_variant_builder_add().

After all the child values are added, g_variant_builder_end() frees the memory associated with the builder and returns the GVariant that was created.

This function completely ignores the previous contents of builder. On one hand this means that it is valid to pass in completely uninitialised memory. On the other hand, this means that if you are initialising over top of an existing GVariantBuilder you need to first call g_variant_builder_clear() in order to avoid leaking memory.

You must not call g_variant_builder_ref() or g_variant_builder_unref() on a GVariantBuilder that was initialised with this function. If you ever pass a reference to a GVariantBuilder outside of the control of your own code then you should assume that the person receiving that reference may try to use reference counting; you should use g_variant_builder_new() instead of this function.
