Re: those nasty file descriptors (fwd)

[sa...@c2.org]

	Looks like he's running Solaris 2.5. Also, it appears from the
truss below, that an open() happily returns an fd > 255, but a
socket() call fails. This 'truss' is near this segment in http_main.c:

    reinit_scoreboard(pconf);
    
    default_server_hostnames (server_conf);

    if ((sd = socket(AF_INET,SOCK_STREAM,IPPROTO_TCP)) == -1) {
        fprintf(stderr,"httpd: could not get socket\n");
        perror("socket");
        exit(1);
    }

	So, in Solaris socket() isn't a syscall, but a wrapper around
another syscall? I suppose my BSD bias shows through here. I don't see
a socket() syscall in this truss log, but the socket() call is
returning a -1.
