Attribute VB_Name = "SFmpqapi" Option Explicit ' ShadowFlare MPQ API Library. (c) ShadowFlare Software 2002-2009 ' License information for this code is in license.txt and ' included in this file at the end of this comment. ' All functions below are actual functions that are part of this ' library and do not need any additional dll files. It does not ' even require Storm to be able to decompress or compress files. ' This library emulates the interface of Lmpqapi and Storm MPQ ' functions, so it may be used as a replacement for them in ' MPQ extractors/archivers without even needing to recompile ' the program that uses Lmpqapi or Storm. It has a few features ' not included in Lmpqapi and Storm, such as extra flags for some ' functions, setting the locale ID of existing files, and adding ' files without having to write them somewhere else first. Also, ' MPQ handles used by functions prefixed with "SFile" and "Mpq" ' can be used interchangably; all functions use the same type ' of MPQ handles. You cannot, however, use handles from this ' library with storm or lmpqapi or vice-versa. Doing so will ' most likely result in a crash. ' Revision History: ' (Release date) 1.08 (ShadowFlare) ' - Fixed a buffer overflow that would occur when reading files ' if neither using a buffer that is large enough to contain the ' entire file nor has a size that is a multiple of 4096 ' - Added SFileOpenFileAsArchive which opens an archive that is ' contained within an already open archive ' - Added MpqRenameAndSetFileLocale and MpqDeleteFileWithLocale. ' These have extra parameters that allow you to use them with ' files having language codes other than what was last set ' using SFileSetLocale ' - Fixed a bug that caused (listfile) to get cleared if adding ' files with a locale ID other than 0 ' - Added MpqOpenArchiveForUpdateEx which allows creating ' archives with different block sizes ' - SFileListFiles can list the contents of bncache.dat without ' needing an external list ' 06/12/2002 1.07 (ShadowFlare) ' - No longer requires Storm.dll to compress or decompress ' Warcraft III files ' - Added SFileListFiles for getting names and information ' about all of the files in an archive ' - Fixed a bug with renaming and deleting files ' - Fixed a bug with adding wave compressed files with ' low compression setting ' - Added a check in MpqOpenArchiveForUpdate for proper ' dwMaximumFilesInArchive values (should be a number that ' is a power of 2). If it is not a proper value, it will ' be rounded up to the next higher power of 2 ' 05/09/2002 1.06 (ShadowFlare) ' - Compresses files without Storm.dll! ' - If Warcraft III is installed, this library will be able to ' find Storm.dll on its own. (Storm.dll is needed to ' decompress Warcraft III files) ' - Fixed a bug where an embedded archive and the file that ' contains it would be corrupted if the archive was modified ' - Able to open all .w3m maps now ' 29/06/2002 1.05 (ShadowFlare) ' - Supports decompressing files from Warcraft III MPQ archives ' if using Storm.dll from Warcraft III ' - Added MpqAddFileToArchiveEx and MpqAddFileFromBufferEx for ' using extra compression types ' 29/05/2002 1.04 (ShadowFlare) ' - Files can be compressed now! ' - Fixed a bug in SFileReadFile when reading data not aligned ' to the block size ' - Optimized some of SFileReadFile's code. It can read files ' faster now ' - SFile functions may now be used to access files not in mpq ' archives as you can with the real storm functions ' - MpqCompactArchive will no longer corrupt files with the ' MODCRYPTKEY flag as long as the file is either compressed, ' listed in "(listfile)", is "(listfile)", or is located in ' the same place in the compacted archive; so it is safe ' enough to use it on almost any archive ' - Added MpqAddWaveFromBuffer ' - Better handling of archives with no files ' - Fixed compression with COMPRESS2 flag ' 15/05/2002 1.03 (ShadowFlare) ' - Supports adding files with the compression attribute (does ' not actually compress files). Now archives created with ' this dll can have files added to them through lmpqapi ' without causing staredit to crash ' - SFileGetBasePath and SFileSetBasePath work more like their ' Storm equivalents now ' - Implemented MpqCompactArchive, but it is not finished yet. ' In its current state, I would recommend against using it ' on archives that contain files with the MODCRYPTKEY flag, ' since it will corrupt any files with that flag ' - Added SFMpqGetVersionString2 which may be used in Visual ' Basic to get the version string ' 07/05/2002 1.02 (ShadowFlare) ' - SFileReadFile no longer passes the lpOverlapped parameter it ' receives to ReadFile. This is what was causing the function ' to fail when used in Visual Basic ' - Added support for more Storm MPQ functions ' - GetLastError may now be used to get information about why a ' function failed ' 01/05/2002 1.01 (ShadowFlare) ' - Added ordinals for Storm MPQ functions ' - Fixed MPQ searching functionality of SFileOpenFileEx ' - Added a check for whether a valid handle is given when ' SFileCloseArchive is called ' - Fixed functionality of SFileSetArchivePriority when multiple ' files are open ' - File renaming works for all filenames now ' - SFileReadFile no longer reallocates the buffer for each block ' that is decompressed. This should make SFileReadFile at least ' a little faster ' 30/04/2002 1.00 (ShadowFlare) ' - First version. ' - Compression not yet supported ' - Does not use SetLastError yet, so GetLastError will not return any ' errors that have to do with this library ' - MpqCompactArchive not implemented ' Any comments or suggestions are accepted at blakflare@hotmail.com (ShadowFlare) ' License information: ' Copyright (c) 2002-2009, ShadowFlare ' All rights reserved.
