I have problems with debugging, so a quick help would be appreciated,
as I cannot figure this out after several hours of digging.

Cygwin /usr/bin/stat returns "Birth: -" for some files. Which value
must the CreationTime member of FILE_BASIC_INFORMATION have to cause
/usr/bin/stat ti return "-"? 0, -1, or something else?


=> tv_nsec < 0



Thank you

But how can tv_nsec become negative (tv_nsec < 0)? That can only
happen if BasicInformation.CreationTime.QuadPart is negative, right?

Caller or application can set 0 to mean keep/return current value, caller or driver can set -1 to mean don't update/return current value:


Take care. Thanks, Brian Inglis              Calgary, Alberta, Canada
