PThread threading library for RISC OS

This library is designed to be compatible with pthread.lib which is used on various UNIX like operating systems. PThreads are also used in the NSPR library, which is what Mozilla uses. As it says in the Mozilla porting docs it is a good idea to try and port NSPR before trying the whole application.
Information on programming with the pthread library is really beyond the scope of this site however there is an excellent resource at the Single UNIX Specification.
