.SH NAME
libpthread \- POSIX threads library
.SH SYNOPSIS
.LP
.nf
cc -mt [ \fIflag\fR... ] \fIfile\fR... \fB-lpthread\fR [ \fB -lrt \fR \fIlibrary\fR... ]
.fi

.SH DESCRIPTION
.LP
Historically, functions in this library provided POSIX threading support. See
\fBstandards\fR(5). This functionality now resides in \fBlibc\fR(3LIB).
.LP
This library is maintained to provide backward compatibility for both runtime
and compilation environments. The shared object is implemented as a filter on
\fBlibc.so.1\fR. New application development need not specify \fB-lpthread\fR
although doing so has no effect.
.SH INTERFACES
.LP
The shared object \fBlibpthread.so.1\fR provides the public interfaces defined
below. See \fBIntro\fR(3) for additional information on shared object
interfaces.
