Free a #SoupXMLRPCParams returned by soup_xmlrpc_parse_request().
Parse method parameters returned by soup_xmlrpc_parse_request().
Deserialization details:
signature is provided, <int> and <i4> can be deserialized
to byte, int16, uint16, int32, uint32, int64 or uint64. Otherwise
it will be deserialized to int32. If the value is out of range
for the target type it will return an error.signature could define
another value type (e.g. "a{ss}").signature could define
another element type (e.g. "as") or could be a tuple (e.g. "(ss)").signature is provided it must have the generic "v" type, which
means there is no guarantee that it's actually a datetime that has been
received. soup_xmlrpc_variant_get_datetime() must be used to parse and
type check this special variant.signature must not have maybes, otherwise an error is returned.A valid #GVariant type string, or %NULL
Opaque structure containing XML-RPC methodCall parameter values. Can be parsed using soup_xmlrpc_params_parse() and freed with soup_xmlrpc_params_free().
