Eric said String list contains additional JSON structure.
At least, it works.
===================== using StringList
'*unicast': ['String'],
'*multicast': ['String']
{
"return": [
{
"name": "virtio-net-pci.0",
"multicast": [
{
"str": "01:80:c2:00:00:21"
},
{
"str": "00:00:00:00:00:00"
}
]
},
....
]
}
======================== using strList
'*unicast': ['str'],
'*multicast': ['str']
Eric, is it expected format?
{
"return": [
{
"name": "virtio-net-pci.0",
"multicast": [
"str": "01:80:c2:00:00:21",
"str": "00:00:00:00:00:00"
]
},
....
]
}
========================
I changed qapi scripts to define struct, struct list,
visit/free functions for 'str'. But it conflicts with
existed str functions. I hadn't find a solution.
Do we need to defind strList & visit functions in qapi-core files?
not generated by scripts.
