Hey avro users,

I'm using a record like this

{
    "type" : "record", 
    "name" : "TestPacket", 
    "fields" : [
        { "name" : "Id" , "type" : "int"},
        { "name" : "Value" , "type" : ["string","null"]}
	]
}

But if I just not write anything to the 'Value' filed,
avro_writer_memory() refuses to validate it. How do you normally use the
optional fields with the C-API?

Regards,

	Markus
