The POSIX Threads Library is Compaq's multithreading run-time
library package. It offers access to library routines via several
interfaces. The Threads Library offers two primary interfaces:
o The PTHREAD multithreading interface is Compaq's
implementation of the IEEE POSIX 1003.1c-1995 standard. Use
this interface to build portable, multithreaded applications.
o The Compaq proprietary TIS interface offers routines that
provide "thread-independent services." These routines
allow a program to perform (or a library to offer) thread-
safe processing that requires synchronization, but without
requiring the use of threads.
A thread is a single, sequential flow of control within a
program. Use threads to improve a program's performance-that
is, its throughput, computational speed, responsiveness, or some
combination. Multiple threads are useful in a multiprocessor
system, where a program's threads can run concurrently on
separate processors. On single-processor systems, multiple
threads can also improve a program's performance by permitting
the overlap of input, output, or other slow operations with
computational operations. For more information see the Guide
to the POSIX Threads Library documentation.
