The following SaveAppSettings(), QueryAppSettings() and InitAppRegKey() are helper functions. This is merely a base Registry skeleton for Utility Manager as more work on it has to come later. --- base/applications/utilman/CMakeLists.txt | 1 + base/applications/utilman/precomp.h | 46 ++++++- base/applications/utilman/registry.c | 202 +++++++++++++++++++++++++++++++ 3 files changed, 248 insertions(+), 1 deletion(-)
