Chapter 33: Threads: Further Details

This chapter provides further details on various aspects of POSIX threads. We discuss the interaction of threads with aspects of the traditional Unix API; in particular, signals and the process control primitives (fork(), exec(), and _exit()). We also provide an overview of the two POSIX threads implementations available on Linux--LinuxThreads and NPTL--and discuss where each of these implementations deviates from the SUSv3 specification of Pthreads.
