# SYNOPSIS
|
|
#
|
|
# LIB_SOCKET_NSL
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# This macro figures out what libraries are required on this platform
|
|
# to link sockets programs.
|
|
#
|
|
# The common cases are not to need any extra libraries, or to need
|
|
# -lsocket and -lnsl. We need to avoid linking with libnsl unless we
|
|
# need it, though, since on some OSes where it isn't necessary it
|
|
# will totally break networking. Unisys also includes gethostbyname()
|
|
# in libsocket but needs libnsl for socket().
