Thread: "bus error"

I am trying to write a server program and a client program that can communicate with eachother. I am trying to use the select() system call to be able to read from the terminal as well. I have tracked the point of crashing to the following lines of code, but can't figure out what the problem is:

Code:

fd_set readset, temp_readset;


  FD_ZERO(&readset);   
 
  //Problem RIGHT HERE:

  FD_SET(receive_fd, &readset); 
  temp_readset = readset;

The program crashes with a "bus error" even with the code that uses select() commented out. Furthermore, if I comment out all of the above lines, the program runs fine. I have included the necessary header files. Any clues as to what is going on? Thanks.

Are you sure that receive_fd contains a sane value?

Thanks , for some reason, I had set the file descriptor with a -1.
