Thanks for your prompt reply. I changed the code to wadd_common_attributes()
but the log still did not get created. Am I right in mentioning the strings
like TimeStamp with L"TimeStamp" and ketwords::file_name =
L"C:\\test\\test.log" during initialization. One warning that I get during
compilation is the following. Does the following relevant to my problem? I
noticed I got the same warning when compiling for normal character as well.

Appreciate your helpful response.

Thanks,
