Subject: [PATCH 03/16] :qemuMonitorJSONMakeCommandInternal: Clear @arguments
|
|
when stolen
|
|
|
|
All callers of qemuMonitorJSONMakeCommandInternal will benefit from
|
|
making @arguments a double pointer and passing it to
|
|
virJSONValueObjectCreate directly which will clear it if it steals the
|
|
value.
