LZCreateFileW

[czerny]

I have found in the export table of Kernel32 the function LZCreateFileW.

This is not documented. It is obviously a companion function to the LZxxx functions for file compression.

I have found the following declaration:

Code Select Expand

ULONG WINAPI LZCreateFileW (IN LPCWSTR FileName,
IN DWORD dwDesiredAccess,
IN DWORD dwShareMode,
IN DWORD dwCreationDisposition,
IN LPWSTR lpString1 );

this is similar to CreateFile(). But I can not guess what lpString1 does.

Any ideas?

The name of the file?

Just copy filename to buffer even read first 14 bytes from file compressed with option -R

That is the first parameter.

That function just copy 1. parameter as filename to 4. parameter as string buffer.
Test file was packed with compress.exe option -R so there was information of last char for filename 'l'
lz32.dl_ -> lz32.dll
