/* ¦ 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. |
