Port 80
# Listen: the Internet address to bind(2) to. If you leave it out,
# it takes the behavior before 0.93.17.2, which is to bind to all
# addresses (INADDR_ANY). You only get one "Listen" directive,
变成Port 8080
# Listen: the Internet address to bind(2) to. If you leave it out,
# it takes the behavior before 0.93.17.2, which is to bind to all

现在发现每次第一次修改的时候这一行没问题，但是下面的注释的#号没有了，变成
n: the Internet address to bind(2) to. If you leave it out,
# it takes the behavior before 0.93.17.2, which is to bind to all

boa无法重新运行，手动改过来以后就没有问题，但是为什么第一次就不行？
system("/usr/bin/killall boa");
boa=fopen("/etc/boa.conf","rt+");
while(fgets(buf,255,boa)!= NULL)
{
if(buf[0]=='#')
continue;
p=strstr(buf,"Port ");
if(p) {
fseek(boa, (-1)*strlen(buf), SEEK_CUR);
sprintf(buf,"Port %5d\n",runtime.cm.http_port);
fputs(buf,boa);
break;
}
}
fclose(boa);
sprintf(buf, "/usr/sbin/boa -c /etc");
system(buf); | t****t
