void
vips_value_set_array (
  GValue* value,
  int n,
  GType type,
  size_t sizeof_type
)

Set value to be an array of things.

This allocates memory but does not initialise the contents: get the pointer and write instead.

`value`	`GValue`
	%GValue to set.
	The argument will be set by the function.
	The data is owned by the caller of the function.
`n`	`int`
	Number of elements.
`type`	`GType`
	The type of each element.
`sizeof_type`	`size_t`
	The sizeof each element.
