I think that you shouldn't be able to have two <shmem/> elements in
the same domain, and since the name is mandatory, STREQ() should be
enough to check whether you need to return current 'i'.
Okay, i agree use STREQ() instead of STRNEQ_NULLABLE. BTW I think one
guest could have more than one <shmem/> element, maybe one is
non-server shmem and another is server shmem, it depends on how to use
it.
Maybe this function could have a bool parameter (something like a
'full_match') that would say whether everything must match or the name
is enough. And it the bool is false, streq is enough, but if it's
true, you could abstract the internals of this for body into
virDomainShmemEquals() or something and that would be called instead.
Good idea, this way is okay to me.
Thanks a lot for your opinion.
