Currently, the Host object looks like
struct _virStorageNetHostDef {
char *name;
char *port;
int transport; /* virStorageNetHostTransport */
char *socket; /* path to unix socket */
}
We don't actually need a 'name' and 'port' if the transport type is
unix
domain sockets, and if the transport is inet tcp/rdma we don't actually
care for socket path.
With a simple union discrimination we can make this much better
struct _virStorageNetHostUnixSockAddr {
char *path;
};
struct _virStorageNetHostInetSockAddr {
char *addr;
char *port;
};
struct _virStorageNetHostDef {
virStorageNetHostTransport type;
union { /* union tag is @type */
virStorageNetHostUnixSockAddr uds;
virStorageNetHostInetSockAddr inet;
} u;
};
This patch performs the required changes in transforming _virStorageNetHostDef
to fit union discrimination.
