9.9.  One Write --> One Read?

Server:

 ...
49      
50      void work(int fd)
51      {       
52              write(fd, "a", strlen("a" ) );
53              write(fd, "bb", strlen("bb" ) );
54              write(fd, "ccc", strlen("ccc" ) );
55              write(fd, "dddd", strlen("dddd" ) );
56              write(fd, "eeeee", strlen("eeeee" ) );
57              write(fd, "ffffff", strlen("ffffff" ) );
58              write(fd, "ggggggg", strlen("ggggggg" ) );
59              write(fd, "", 0 );
60              
61      }
 ...

Client:

 ...
50      int main(int argc, char **argv)
51      {
52              int     fd, n;
53              char    data[10];
54      
55              if (argc != 2 )
56                      fprintf(stderr, "%s: %s host\n",
57                              argv[0], argv[0] ),
58                      exit(1);
59      
60              fd = hp_open_tcp_client_con( argv[1], PORT );
61              while  ( (n = read(fd, data, sizeof(data) - 1 )) > 0)   {
62                      data[n] = '\0';
63                      printf("%d: --%s-- (n = %d)\n", (int)getpid(), data, n );
64              }
65              
66              if ( n < 0 )
67                      perror("read error"), exit(1);
68      
69              close(fd);
70              exit(0);
71      }
 ...

Result:

# server first
