tcp server problems

[Foxy999]

This is my code, I want to be able to keep receiving data while I can send data, so I used fork(). But for some reason it is not working, it will only recv once. I am new to network programming, please help.

                char buf[10000];
                pid_t pid;
		pid = fork();
		if(pid == 0)
		{
			while(1)
			{
				sleep(1);
				memset(buf, '\0', sizeof(buf));
				recv(clntSock, buf, sizeof(buf), 0);
				printf("%s", buf);
			}
		}
		else
		{
			while(1)
			{
				sleep(1);
				memset(buf, '\0', sizeof(buf));
				fgets(buf, sizeof(buf), stdin);
				buf[strlen(buf) - 1] = '\0';
				send(clntSock, buf, strlen(buf), 0);
			}
		}

How do you know what is working and what isn't, when you ignore the status results for
- fgets
- send
- recv

Plus, if you want us to actually test the code say, you need to post a complete program.
Not the random snippet where you think the problem is.
