Since error_vprintf is in monitor.o this allows a stub error_vprintf impl to be used that calls g_test_message. This takes a different approach, with error_vprintf moving back to error-report.c such that it is always linked into the tests. The monitor_vprintf() stub is then changed to use g_test_message if QTEST_SILENT_ERRORS is set, otherwise it will return -1 and trigger error_vprintf to call vfprintf. The end result is functionally equivalent for the purposes of the unit tests. Reviewed-by: Richard Henderson Reviewed-by: Eric Blake Reviewed-by: Markus Armbruster Signed-off-by: Daniel P.
