GetExpandedNameA function

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

Syntax

INT GetExpandedNameA(
  LPSTR lpszSource,
  LPSTR lpszBuffer
);

Parameters

lpszSource

The name of the compressed file.

lpszBuffer

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.
