From 48825ca419fd9c8140d4fecb24e982d68ebca74f Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Wed, 13 Jul 2016 21:50:19 -0600 Subject: qapi: Plumb in 'boxed' to qapi generator lower levels The next patch will add support for passing a qapi union type as the 'data' of a command. But to do that, the user function for implementing the command, as called by the generated marshal command, must take the corresponding C struct as a single boxed pointer, rather than a breakdown into one parameter per member. Even without a union, being able to use a C struct rather than a list of parameters can make it much easier to handle coding with QAPI. This patch adds the internal plumbing of a 'boxed' flag associated with each command and event. In several cases, this means adding indentation, with one new dead branch and the remaining branch being the original code more deeply nested; this was done so that the new implementation in the next patch is easier to review without also being mixed with indentation changes. For this patch, no behavior or generated output changes, other than the testsuite outputting the value of the new flag (always False for now).
