from c/c++ you will use pthread_cancel(), see the ref manual
http://www.qnx.com/developers/docs/6.4.0/neutrino/lib_ref/p/pthread_cancel.html

from what I know there is no cmd line utilty that gives you this option.
You can use slay -T<tid> to get a signal delivered to specific thread, but that's something different ...
