Routine Description:
|
|
|
|
This routine moves a file, which may be a copy or a rename.
|
|
|
|
Arguments:
|
|
|
|
WorkContext - a pointer to the work context block for the operation. The
|
|
Session, TreeConnect, and RequestHeader fields are used.
|
|
|
|
TargetShare - a pointer to the share on which the target should
|
|
be. The RootDirectoryHandle field is used to do relative opens.
|
|
|
|
SmbOpenFunction - the "OpenFunction" field of the request SMB. This
|
|
parameter is used to determine what should be done if the target
|
|
file does or does not exist.
|
|
|
|
SmbFlags - a pointer to the "Flags" field of the request SMB. This
|
|
parameter is used to determine whether we know that the target
|
|
is supposed to be a file or directory. In addition, if this has
|
|
no information about the target, it is set to reflect whether
|
|
the target was a directory or file. This is useful when doing
|
|
multiple renames or copies as a result of wildcards--move a*.* b
|
|
might call this routine many times, and if b is a directory,
|
|
this routine will set this parameter appropiately such that if
|
|
does not have to reopen the directory for each move.
|
|
|
|
SmbSearchAttributes - the search attributes specified in the request
|
|
SMB. The attributes on the source file are checked against
|
|
these to make sure that the move can be done.
|
|
|
|
FailIfTargetIsDirectory - if TRUE and the target already exists as
|
|
a directory, fail the operation. Otherwise, rename the file
|
|
into the directory.
|
|
|
|
InformationLevel - Move/Rename/CopyOnWrite/Link/MoveCluster
|
|
|
|
ClusterCount - MoveCluster count
|
|
|
|
Source - a pointer to a string describing the name of the source file
|
|
relative to the share directory in which it is located.
|
|
|
|
Target - a pathname to the target file. This may contain directory
|
|
information--it should be the raw information from the SMB,
|
|
unadulterated by the SMB processing routine except for
|
|
canonicalization. This name may end in a directory name, in
|
|
which case the source name is used as the filename.
|

Return Value:
|
|
|
|
Status.

Routine Description:

|
|
|
This routine sets up for a call to SrvCopyFile. It opens the target,

|
determining, if necessary, whether the target is a file or directory.
|
|
If this information is unknown, it writes it into the SmbFlags

location.
|
|
|
|
Arguments:
|
|
|
|
WorkContext - a pointer to the work context block for the operation.
|
|
The session pointer is used, and the block itself is used for
|
|
an impersonation.
|
|
|
|
Source - the name of the source file relative to its share.
|
|
|
|
SourceHandle - the handle to the source file.
|
|
|
|
Target - the name of the target file relative to its share.
|
|
|
|
TargetShare - the share of the target file. The RootDirectoryHandle
|
|
field is used for a relative rename.
|
|
|
|
SmbOpenFunction - describes whether we are allowed to overwrite an
|
|
existing file, or we should append to existing files.
|
|
|
|
SmbFlags - can tell if the target is a file, directory, or unknown.
|
|
This routine writes the true information into the location if

|
it is unknown.

Routine Description:
|
|
|
|
This routine does the actual rename of an open file. The target may
|
|
be a file or directory, but is bound by the constraints of SmbFlags.
|
|
If SmbFlags does not indicate what the target is, then it is first
|
|
assumed to be a file; if this fails, then the rename if performed
|
|
again with the target as the original target string plus the source
|
|
base name.
|
|
|
|
*** If the source and target are on different volumes, then this
|
|
routine will fail. We could make this work by doing a copy
|
|
then delete, but this seems to be of limited usefulness and
|
|
possibly incorrect due to the fact that a big file would take
|
|
a long time, something the user would not expect.
|
|
|
|
Arguments:
|
|
|
|
WorkContext - a pointer to the work context block for this operation
|
|
used for an impersonation.
|
|
|
|
Source - the name of the source file relative to its share.
|
|
|
|
SourceHandle - the handle to the source file.
|
|
|
|
Target - the name of the target file relative to its share.
|
|
|
|
TargetShare - the share of the target file. The RootDirectoryHandle
|
|
field is used for a relative rename.
|
|
|
|
SmbOpenFunction - describes whether we are allowed to overwrite an
|
|
existing file.
|
|
|
|
SmbFlags - can tell if the target is a file, directory, or unknown.
|
|
This routine writes the true information into the location if
|
|
it is unknown.
|
|
|
|
FailIfTargetIsDirectory - if TRUE and the target already exists as
|
|
a directory, fail the operation. Otherwise, rename the file
|
|
into the directory.
|
|
|
|
InformationLevel - Rename/CopyOnWrite/Link/MoveCluster
|
|
|
|
ClusterCount - MoveCluster count
|
|
|
|

|
|
