SYMPTOMS
When the network client is the real-mode Netware NETX redirector for
Netware 3.11, MoveFile() fails to rename files and directories when the
source and destination names are specified in Universal Naming Convention
(UNC) format. The return value of MoveFile() is FALSE, but GetLastError()
reports an error code of NO_ERROR (0).
The following code demonstrates the problem:
MoveFile ("\\\\testsrv\\testshare\\srcdir",
"\\\\testsrv\\testshare\\destdir");
This problem does not occur with the NETX for Netware 3.12 and later or
with protected-mode Netware clients.
CAUSE
NETX for Netware 3.11 does not support renaming files and directories
using UNC names.
RESOLUTION
There are several possible workarounds for this problem:
- Map a drive letter to the server and share. Then use this drive letter
to do the rename. Use WNetAddConnection() or WNetAddConnection2() to map
the drive letter.
-or- - Copy the source directory (and all subdirectories) to the destination
directory, and then delete the source directory. This operation will be
slow if the source directory contains a lot of files and subdirectories.
-or- - Upgrade to the protected-mode Netware client, or use VLM instead of
NETX.
STATUS
This behavior is by design.
MORE INFORMATION
Although the bug occurs specifically when MoveFile() is used, some
runtime library functions call MoveFile(), and thus exhibit the same
behavior. The most notable is the C runtime library's rename()
function. For information about how your particular compiler's runtime
library implements rename(), refer to the documentation provided with
your compiler.
