No CloseHandle() call is made in both the case. CFile (or for that
reason CStdioFile) Close() method will close the OS file handle.
(closehandle() in the sample code is commented given can be ignored)
Just to make it a bit more clearer, the executable (for testing i just
put the sample code above inside a for loop of 1000) is run from a
win2k3 server and xp machine. XP shows no handle increase leak (handle
count of 85), but in Win2k3 the handle count was around 1085 ( for
1000 iterations). This information i got from the windows task
manager. Upon this, i tried the procexp tool from sysinternals. This
clearly showed that the Handle being leaked is a file handle,
\\TestServer\TestShare in our case. (This is not the file as such but
BTW, my samba server is on Solaris 9.
Please let me know if you erquire any further information...
