'use Socket' is a perl5-ism, so we wrap it in an - # eval, and if it fails we try 'require "sys/socket.ph"'. If this fails, - # we just guess at the values. If you find perl moaning here, just - # hard-code the values of AF_INET and SOCK_STREAM. You can find these out - # for your platform by looking in /usr/include/sys/socket.h and related - # files. - # - - chop($os = `uname`); - chop($osrev = `uname -r`); - - eval 'use Socket'; - if ($@) { - eval 'require "sys/socket.ph"'; - if ($@) { - if (($os eq "SunOS") && ($osrev !~ /^4/)) { - $AF_INET = 2; - $SOCK_STREAM = 2; - } else { - $AF_INET = 2; - $SOCK_STREAM = 1; - } - } else { - $AF_INET = &AF_INET; - $SOCK_STREAM = &SOCK_STREAM; - } - } else { - $AF_INET = &AF_INET; - $SOCK_STREAM = &SOCK_STREAM; - } -} |
