Here is a small example demonstrating the use of data decompression library functions.

format PE CONSOLE 4.0



include  'include\macro\stdcall.inc'

include  'include\macro\import.inc'

include  'include\Lz32.inc'



section  '.data' data readable writeable



mylzfile db 'CrazyWnd.lz',0

output  db 'CrazyWnd.exe',0



section '.code' code readable executable



entry 	 start



start:



stdcall  decompress,mylzfile,output

invoke   ExitProcess,0



proc      decompress,LzFile,decompressed

ofs              OFSTRUCT

ofd              OFSTRUCT    

hFileSrc       dd ?

hFileDest    dd ?

enter

lea         eax,[ofs]

invoke   LZOpenFile,[LzFile],eax,OF_READ

mov       [hFileSrc],eax

lea         eax,[ofd]

invoke   LZOpenFile,[decompressed],eax,OF_CREATE

mov       [hFileDest],eax

invoke   LZCopy,[hFileSrc],[hFileDest]

invoke   LZClose,[hFileSrc]

invoke   LZClose,[hFileDest]

return
