Re: Allocating a thread to a specific processor core

John, 
I notice your question came via the old Red Hat sourceware repository mailing list. The project moved to sourceforge several years ago.
The current head revision at
https://sourceforge.net/p/pthreads4w/wiki/Home/
(code at)
https://sourceforge.net/p/pthreads4w/code/ci/master/tree/
provides the following functions:
pthread_attr_getaffinity_nppthread_attr_setaffinity_nppthread_getaffinity_nppthread_setaffinity_np
and supporting  macros/functions:
CPU_ZEROCPU_EQUALCPU_COUNTCPU_SETCPU_CLRCPU_ISSETCPU_ANDCPU_ORCPU_XOR
They follow the Linux functions of the same name. See the manual pages included in the code repository.
In case you're looking for binary versions of the library,  the Sourceforge project doesn't produce built versions of the library anymore, assuming that users will be able to and prefer to build their own.

When using 'pthread_create()' (on Windows) is it possible to specify a 
preferred processor/core for the thread to run on (in the attributes maybe?)

Windows itself has a function for doing this but I just wondered if 
there's anything similar that's already available in libpthread?
