[Interest] old style cast

[Damian Ivanov]

Hello,

What is the correct way to do the following so it doesn't warn about
the use of old stylecast?
//G_VARIANT_TYPE_BYTESTRING = is defined in gvarianttype.h
// #define G_VARIANT_TYPE_BYTESTRING           ((const GVariantType *) "ay")
// value is of type GVariant *value

if (g_variant_is_of_type(value, G_VARIANT_TYPE_BYTESTRING)) // warn:
use of old style cast

Thank you for suggestions.

Regards,
Damian
