GetExpandedName function

Retrieves the original name of a compressed file, if the file was compressed by the Lempel-Ziv algorithm.

Syntax


INT WINAPI GetExpandedName(
  _In_  LPTSTR lpszSource,
  _Out_ LPTSTR lpszBuffer
);

Parameters

lpszSource [in]

The name of the compressed file.

lpszBuffer [out]

A pointer to a buffer that receives the original name of the compressed file.

Return value

If the function succeeds, the return value is 1.

If the function fails, the return value is LZERROR_BADVALUE. There is no extended error information for this function; do not call GetLastError.

Note  GetExpandedName calls neither SetLastError nor SetLastErrorEx; thus, its failure does not affect a thread's last-error code.

Remarks

The contents of the buffer pointed to by the lpszBuffer parameter is the original file name if the file was compressed by using the /r option. If the /r option was not used, this function duplicates the name in the lpszSource parameter into the lpszBuffer buffer.
