Modified: ha_connect.cc (MakeRecord) Moved PlgAllocResult to plgdbutl.cpp Modified: mycat.cpp plgdbutl.cpp Continuing implementing the "catalog" tables (ex "info"). Already existing were the ODBC data source table and the WMI column info table. The common way to handle them was modified to enable each table types to send personalized data. Now takes care of all existing catalog functions for table types that can retrieve and use such information. Modified: ha_connect.cc odbconn.cpp tabodbc.h tabodbc.cpp tabfmt.h tabfmt.cpp tabmysql.h tabmysql.cpp tabwmi.h tabwmi.cpp myconn.h myconn.cpp filamdbf.cpp plgdbsem.h reldef.h reldef.cpp tabdos.h tabdos.cpp tabfix.h xtable.h table.cpp
