Chapter 10. Future standardization

Chapter 10. Future standardization

Three primary standardization efforts affect Pthreads programmers. X/Open’s XSH5 is a new interface specification that includes POSIX.1b, Pthreads, and a set of additional thread functions (part of the Aspen fast-track submission). The POSIX.1j draft standard proposes to add barriers, read/write locks, spinlocks, and improved support for “relative time” waits on condition variables. The POSIX.14 draft standard (a “POSIX Standard Profile”) gives direction for managing the various options of Pthreads in a multiprocessor environment.
