From: ShadowFlare Date: Tue, 5 Jan 2010 09:12:48 +0000 (-0700) Subject: More work on large archives and code reorganization. X-Git-Url: https://sfsrealm.hopto.org/projects/gitweb.cgi?a=commitdiff_plain;h=212e7d696e798215d4cddfcb5007c212814728e6;p=SFmpqapi.git More work on large archives and code reorganization. - Split some code for archive opening and creation into separate functions. - Moved header writing into separate function. - Large archive reading should be complete. - Large archive compacting may be complete. - Some work on adding files to large archives, but it is still incomplete and will likely corrupt. - Other large archive write operations should be complete. - SFileFindMpqHeader now takes archive handles and archive file handles. --- diff --git a/MpqBlockTable.cpp b/MpqBlockTable.cpp index e351f05..99238da 100644 --- a/MpqBlockTable.cpp +++ b/MpqBlockTable.cpp @@ -9,6 +9,7 @@ BOOL WriteBlockTable(MPQARCHIVE *mpqOpenArc) { DWORD tsz;
