Chapter 4 Linux Technical Information
4.1 Linux Threading Environments
On Linux platforms, two different threading libraries may be available, based on your vendor: either the GNU LinuxThreads implementation, or the Native POSIX Threading Library (NPTL). In general, these libraries are compatible with each other, and the sections in this chapter on the POSIX implementation are relevant to both. For the areas in which they differ, see Section 4.4.
