LZCopy info  Overview  Group

The LZCopy function copies a source file to a destination file. If the source file is compressed with the Microsoft File Compression Utility (COMPRESS.EXE), this function creates a decompressed destination file. If the source file is not compressed, this function duplicates the original file.

LONG LZCopy(

Parameters

hfSource

Identifies the source file.

hfDest

Identifies the destination file.

Return Values

If the function succeeds, the return value specifies the size, in bytes, of the destination file.

If the function fails, the return value is an LZERROR_* code. These codes have values less than zero. Note that LZCopy calls neither SetLastError nor SetLastErrorEx; thus, its failure does not affect a thread’s last-error code.

Here is a list of the LZERROR_* codes that LZCopy can return upon failure:

There is no extended error information for this function; do not call GetLastError.

Remarks

The handles identifying the source and destination files must be retrieved by calling the LZInit or LZOpenFile function.

The preferred function to use for copying files is LZCopy. The CopyLZFile function is provided for compatibility with 16-bit versions of Windows.

If the function succeeds, the file identified by the hfDest parameter is always uncompressed.
