why error: "accept: Invalid argument"

[Yarco]

when doing fork in a loop:

while(1) {
tmp_sd = accept(sd, (struct sockaddr*)&tmp_sin, &len);
if (tmp_sd == -1) {
perror("accept");
exit(0);
}
 
//check client ip
 
//fork
pid = fork();
switch(pid) {
case -1:
perror("fork");
break;
case 0:
_exit(0);
}
 
close(tmp_sd);
}
 

If there's no fork, the code done well.
But if fork, when telnet, it has error: accept: Invalid argument
Thanks a lot.

accept() and for() are not standard C functions. (Neither are _exit()
and close().)

Try comp.unix.progr ammer.

We must do something. This is something. Therefore, we must do this.

I've posted it in comp.unix.progr ammer. But nobody answer it.

my code is Ok when compiling.
But when i "telnet" the server, it gets error:
accept: Invalid argument.
Then quit.
But without "fork" process, i "telnet" the server, and the server is
still running.

You posted less than 4 hours ago. Be patient. It's still off-topic here.
