-dnl

-dnl
-dnl effectively does:

-dnl if CacheVar == yes
-dnl AC_MESSAGE_RESULT(yes)

-dnl Usage:

-dnl AC_LIBRARY_NET: #Id: net.m4,v 1.5 1997/11/09 21:36:54 jhawk Exp #
-dnl
-dnl Written by John Hawkinson <jhawk@mit.edu>. This code is in the Public
-dnl Domain.
-dnl
-dnl This test is for network applications that need socket() and
-dnl gethostbyname() -ish functions. Under Solaris, those applications need to
-dnl link with "-lsocket -lnsl". Under IRIX, they should *not* link with
-dnl "-lsocket" because libsocket.a breaks a number of things (for instance:
-dnl gethostbyname() under IRIX 5.2, and snoop sockets under most versions of
-dnl IRIX).
-dnl
-dnl Unfortunately, many application developers are not aware of this, and
-dnl mistakenly write tests that cause -lsocket to be used under IRIX. It is
-dnl also easy to write tests that cause -lnsl to be used under operating
-dnl systems where neither are necessary (or useful), such as SunOS 4.1.4, which
-dnl uses -lnsl for TLI.
-dnl
-dnl This test exists so that every application developer does not test this in
-dnl a different, and subtly broken fashion.
-dnl
-dnl It has been argued that this test should be broken up into two seperate
-dnl tests, one for the resolver libraries, and one for the libraries necessary
-dnl for using Sockets API. Unfortunately, the two are carefully intertwined and
-dnl allowing the autoconf user to use them independantly potentially results in
-dnl unfortunate ordering dependancies -- as such, such component macros would
-dnl have to carefully use indirection and be aware if the other components were
-dnl executed. Since other autoconf macros do not go to this trouble, and almost
-dnl no applications use sockets without the resolver, this complexity has not
-dnl been implemented.
-dnl
-dnl The check for libresolv is in case you are attempting to link statically
-dnl and happen to have a libresolv.a lying around (and no libnsl.a).
