/* ¦ Duplicate a file and optionally rename it.
|
|
The FileCopy function duplicates a file and optionally renames it.
|
|
Since the PBHCopyFile routine is only available on some
|
|
AFP server volumes under specific conditions, this routine
|
|
either uses PBHCopyFile, or does all of the work PBHCopyFile
|
|
does. The srcVRefNum, srcDirID and srcName are used to
|
|
determine the location of the file to copy. The dstVRefNum
|
|
dstDirID and dstPathname are used to determine the location of
|
|
the destination directory. If copyName <> NIL, then it points
|
|
to the name of the new file. If copyBufferPtr <> NIL, it
|
|
points to a buffer of copyBufferSize that is used to copy
|
|
the file's data. The larger the supplied buffer, the
|
|
faster the copy. If copyBufferPtr = NIL, then this routine
|
|
allocates a buffer in the application heap. If you pass a
|
|
copy buffer to this routine, make its size a multiple of 512
|
|
($200) bytes for optimum performance.
|
|
|
|
srcVRefNum input: Source volume specification.
|
|
srcDirID input: Source directory ID.
|
|
srcName input: Source file name.
|
|
dstVRefNum input: Destination volume specification.
|
|
dstDirID input: Destination directory ID.
|
|
dstPathname input: Pointer to destination directory name, or
|
|
nil when dstDirID specifies a directory.
|
|
copyName input: Points to the new file name if the file is
|
|
to be renamed or nil if the file isn't to
|
|
be renamed.
|
|
copyBufferPtr input: Points to a buffer of copyBufferSize that
|
|
is used the i/o buffer for the copy or
|
|
nil if you want FileCopy to allocate its
|
|
own buffer in the application heap.
|
|
copyBufferSize input: The size of the buffer pointed to
|
|
by copyBufferPtr.
|
|
preflight input: If true, FileCopy makes sure there are enough
|
|
allocation blocks on the destination volume to
|
|
hold both the data and resource forks before
|
|
starting the copy.
