[Insight-users] ITK Threads with memberfunctions

[Miller, James V (GE, Research)]

Marcus,
 
The pattern I use to have the multithreader call a static function (or a standard C function) and pass the object as part of the clientdata.  The static method, then casts the clientdata back to the object type and calls the member function that I wanted to call.
 
This is how the multithreaded filters are implemented.  Take a look at ImageSource::GenerateData() and ImageSource::ThreaderCallback().

Dear all,
 
I would like to make a programm, at which I'm currenty 
working, multithreaded.
 
As far as I know, there is a class called itkMultiThreader which
provides this functionality.
My question is, if this class can also be used to create a thread
for a memberfunction of an object, because I always receive compiler
complaints from VC6 on std_call problems when I call SetSingleMethod().
 
As far as I know, for example posix threads only work with C-functions.
So, is this also true for the multithreader or may the problem be different?
 
I think that for example, the threads from Boost library can deal with member functions,
but I would not like to use a large library only for one small feature.
Can you please give me a hint?
 
Regards,
Markus
 
PS: declaring the function as static is not possible, 
because it accesses non-static members.
