Queries item at position item_index
in this for the attribute specified by attribute
.
If the attribute exists and matches the VariantType corresponding to
format_string
then format_string
is used to deconstruct the value into the positional parameters and
true is returned.
If the attribute does not exist, or it does exist but has the wrong type, then the positional parameters are ignored and false is returned.
This function is a mix of get_item_attribute_value and
@get, followed by a g_variant_unref
. As such,
format_string
must make a complete copy of the data (since the Variant
may go away after the call to g_variant_unref
). In particular, no '&' characters are allowed in format_string
.
