Additional tests reveal that RTL_QUERY_REGISTRY_DIRECT does work with non-string default values, it just requires a pointer to the value and it doesn't infer the size automatically. That means that the same code can be used to handle both default and non-default values.

Additional tests reveal that RTL_QUERY_REGISTRY_DIRECT does work with non-string default values, it just requires a pointer to the value and it doesn't infer the size automatically. That means that the same code can be used to handle both default and non-default values. --- dlls/ntdll/reg.c | 102 ++++++++++++++++++++--------------------- dlls/ntdll/tests/reg.c | 89 ++++++++++++++++++++++++++--------- 2 files changed, 118 insertions(+), 73 deletions(-)

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
