gvalue_to_gvariant

Converts a Value to a Variant of the type indicated by the type parameter.

The conversion is using the following rules:

• typeof (BusName): 's', 'o', 'g' or 'ay'
• G_TYPE_STRV: 'as', 'ao' or 'aay'
• G_TYPE_BOOLEAN: 'b'
• G_TYPE_UCHAR: 'y'
• G_TYPE_INT: 'i', 'n'
• G_TYPE_UINT: 'u', 'q'
• G_TYPE_INT64 'x'
• G_TYPE_UINT64: 't'
• G_TYPE_DOUBLE: 'd'
• typeof (Variant): Any VariantType

This can fail if e.g. gvalue is of type typeof ( BusName) and type is ['i'][G-VARIANT-TYPE-INT32:CAPS ]. It will also fail for any Type (including e.g. typeof (Object) and BOXED derived-types) not in the table above.

Note that if gvalue is of type typeof ( Variant) and its value is null , the empty Variant instance (never null) for type is returned (e.g. 0 for scalar types, the empty string for string types, '/' for object path types, the empty array for any array type and so on).

See the gvariant_to_gvalue function for how to convert a Variant to a Value.

Parameters:

gvalue	A Value to convert to a Variant
type	A VariantType

Returns:

A Variant (never floating) of VariantType type holding the data from gvalue or null in case of failure. Free with g_variant_unref.
