|
.Nm libthr
|
|
.Nd "alternative POSIX threads library"
|
|
.Sh LIBRARY

.Lb libthr
|
|
.Sh SYNOPSIS
|
|
.In pthread.h
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
library provides an alternative 1:1 implementation of the
|
|
.Xr pthread 3
|
|
library interfaces for application threading.
|
|
While applications may be linked directly against
|
|
.Nm ,
|
|
system administrators are offered maximum flexibility by linking against
|
|
.Xr pthread 3 ,
|
|
as they can then use
|
|
.Xr libmap.conf 5
|
|
to select the threading implementation on a per-application basis.
|
|
.Pp
|
|
.Nm
|
|
has been optimized for use by applications expecting system scope thread
|
|
semantics, and can provide significant performance improvements.
|
|

.Nm
|
|
was originally created by
|
|
.An "Jeff Roberson" Aq jeff@FreeBSD.org ,
|
|
and enhanced by
|
|
.An "Jonathan Mini" Aq mini@FreeBSD.org
|
|
and
|
|
.An "Mike Makonnen" Aq mtm@FreeBSD.org .
|
|
It has been substantially rewritten and optimized by
|
|
.An "David Xu" Aq davidxu@FreeBSD.org .
|
|
.An -split
|
|
.Sh BUGS
|
|
As
|
|
.Nm
|
|
is an optimized system scope thread library, it does not offer support for
|
|
scheduling threads as process scope threads.
