.SH NAME
libnsl \- network services library
.SH SYNOPSIS

.nf
cc [ \fIflag\fR... ] \fIfile\fR... \fB-lnsl\fR [ \fIlibrary\fR... ]
.fi

.SH DESCRIPTION
.sp
.LP
Functions in this library provide routines that provide a transport-level
interface to networking services for applications, facilities for
machine-independent data representation, a remote procedure call mechanism, and
other networking services useful for application programs.
.sp
.LP
Some symbols are not intended to be referenced directly.  Rather, they are
exposed because they are used elsewhere through a private interface.  One such
example is the set of symbols beginning with the \fB_xti\fR prefix. Those
symbols are used in implementing the X/Open Transport Interface (\fBXTI)\fR
interfaces documented in \fBlibxnet\fR. See \fBlibxnet\fR(3LIB).
.SH INTERFACES

The shared object \fBlibnsl.so.1\fR provides the public interfaces defined
below. See \fBIntro\fR(3) for additional information on shared object
interfaces.
