This folder contains compression related files including:
* zip file support based on minizip library (http://www.winimage.com/zLibDll/minizip.html)
including:
* minizip version 1.01e source files
* wrapper functions for minizip
* some additionl functions to provide a higher level API for zip files
Some small changes (to fix compile time warning and errors) are applied to original
source of minizip 1.01e:
* harbour/contrib/hbzlib/zip.c
* added forward definitions of allocate_new_datablock(),
free_datablock(), init_linkedlist(), add_data_in_datablock(),
ziplocal_TmzDateToDosDate()
* pacified warnings of unused args dosDate and crcForCrypting
* fixed 2 warnings: assigned value is not used. See, TOFIX
comment for one of the fixes
* fixed BCC warning "function call with no prototype" by changing
local int zipFlushWriteBuffer(zi)
zip_internal* zi;
{
to
local int zipFlushWriteBuffer(zip_internal* zi)
{
I expected this code be equivavlent! ??? :/
* harbour/contrib/hbzlib/unzip.c
* added forward definitions of strcmpcasenosensitive_internal(),
unzlocal_DosDateToTmuDate(), unzlocal_CheckCurrentFileCoherencyHeader()
* fixed 8 warnings: assigned value is not used. See, TOFIX
comment for one of the fixes
* harbour/contrib/hbzlib/ioapi.c
* pacified 7 warnings: unused args opaque
* fixed warning: assigned value is not used
