[Mono-dev] Creating AppDomains From Embedded Mono

[Zoltan Varga]

                                      Hi,

  MonoDomain is the internal structure used by the runtime to track appdomains,
while MonoAppDomain is the managed AppDomain object itself:

struct _MonoAppDomain {
	MonoMarshalByRefObject mbr;
	MonoDomain *data;
};

The data field of the MonoAppDomain object points to the corresponding
MonoDomain.

                    Zoltan
