[Qemu-devel] [PATCH RFC v4 15/29] qapi: Avoid use of 'data' member of qapi unions |
Date: |
Wed, 9 Sep 2015 22:06:17 -0600 |
qapi code generators currently create a 'void *data' member as
part of the anonymous union embedded in the C struct corresponding
to a qapi union. However, directly assigning to this member of
the union feels a bit fishy, when we can directly use the rest
of the struct instead.
