patch from Stefan Kratochwil <entwicklung@inovel.de> : canfestival-3-fm3_698.patch
Bug:
If an object dictionary entry was requested whose size exceeds
SDO_MAX_LENGTH_TRANSFERT, the memcpy() call at line 139 of objacces.c overwrites
the memory after *pDestData which causes stack corruption.
-> Bugfix:
The bug was corrected by size checking the requested data. An 'Out of
memory' error message will be generated if the requested data exceeds
SDO_MAX_LENGTH_TRANSFERT.
Additional changes:
Added dynamic buffer allocation for the SDO transfer. This feature can be used
if SDO_DYNAMIC_BUFFER_ALLOCATION is defined in config.h. The size of the
dynamically allocated buffer is controlled with
SDO_DYNAMIC_BUFFER_ALLOCATION_SIZE.
-> Note:
This change removes the detection of OD_LENGTH_DATA_INVALID errors!

DYNAMIC LINK LIBRARY : can_copcican_win32 Project Overview
========================================================================
AppWizard has created this can_copcican_win32 DLL for you.
This file contains a summary of what you will find in each of the files that
make up your can_copcican_win32 application.
can_copcican_win32.vcxproj
This is the main project file for VC++ projects generated using an Application Wizard.
It contains information about the version of Visual C++ that generated the file, and
information about the platforms, configurations, and project features selected with the
Application Wizard.
can_copcican_win32.vcxproj.filters
This is the filters file for VC++ projects generated using an Application Wizard.
It contains information about the association between the files in your project
and the filters. This association is used in the IDE to show grouping of files with
similar extensions under a specific node (for e.g. ".cpp" files are associated with the
"Source Files" filter).
can_copcican_win32.cpp
This is the main DLL source file.
When created, this DLL does not export any symbols. As a result, it
will not produce a .lib file when it is built. If you wish this project
to be a project dependency of some other project, you will either need to
add code to export some symbols from the DLL so that an export library
will be produced, or you can set the Ignore Input Library property to Yes
on the General propert page of the Linker folder in the project's Property
Pages dialog box.
/////////////////////////////////////////////////////////////////////////////
Other standard files:
StdAfx.h, StdAfx.cpp
These files are used to build a precompiled header (PCH) file
named can_copcican_win32.pch and a precompiled types file named StdAfx.obj.

Other notes:
AppWizard uses "TODO:" comments to indicate parts of the source code you
should add to or customize.
