I would prefer the secure and generic versions unless you have a strong
preference for the wide char version

You can use fwprintf_s(). I am fine if you want to stay with tchar version. It
is just implementation wise, tchar functions are always mapped to either
Unicode/wchar version or ANSI version. E.g. we have the following definition in
"tchar.h". Because we have explicitly indicate we only support Unicode. I think
it more clear if we always use wide char version of the functions. Either way,
since they are equivalent, it is your call.
{code}
#define _ftprintf_s fwprintf_s
{code}
# For ReportErrorCode(), it is because we are calling FormatMessageW() inside
the function to retrieval the [system error

message inside the function. If you pass in EXIT_FAILURE (1), it will print
error message of ERROR_INVALID_FUNCTION (1).

> ProcfsBasedProcessTree is used by the TaskTracker to get process information
> like memory and cpu usage. This information is used to manage resources etc.
> The current implementation is based on Linux procfs functionality and hence
> does not work on other platforms, specifically windows.
