Subj : pthread library architecture (threading model) To : comp.programming.threads From : pankaj-startup Date : Sun Sep 18 2005 03:42 am Hi, As per my knowledge, posix thread library (pthread) implements M:N model. i.e. multiple user threads (M) multiplexes on a N LWPs. When process runs out of LWPs, kernel notifies pthread library to create a new LWP. This is identical to default solaris thread implementation. What is the difference between pthread lib & solaris default thread library? If anyone point me to good article which explains architecture of pthread lib, it would be of gr8 help. Thanks, Pankaj .
