|
.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.

has been optimized for use by applications expecting system scope thread
|
|
|
|
|
semantics, and can provide significant performance improvements.
