Function

GLibVariantnew_maybe

since: 2.24

Declaration

GVariant*
g_variant_new_maybe (
  const GVariantType* child_type,
  GVariant* child
)

Description

Depending on if child is NULL, either wraps child inside of a maybe container or creates a Nothing instance for the given type.

At least one of child_type and child must be non-NULL. If child_type is non-NULL then it must be a definite type. If they are both non-NULL then child_type must be the type of child.

If child is a floating reference (see g_variant_ref_sink()), the new instance takes ownership of child.
