libthread - threads library
SYNOPSIS
cc -mt [ flag... ] file... [ library... ]
DESCRIPTION
Historically, functions in libthread provided threading support. This functionality now resides in libc(3LIB).
This library is maintained to provide backward compatibility for both runtime and compilation environments. The shared object is imple-
mented as a filter on libc.so.1. New application development need not specify -lthread.
INTERFACES
The shared object libthread.so.1 provides the public interfaces defined below. See intro(3) for additional information on shared object
interfaces.
