Client summary

We're done with the client side of things.

The following are key points to remember:

• The client usually triggers communication with the resource manager via open() (or fopen()).
• Once the client's request has “resolved” to a particular resource manager, we never change resource managers.
• All further messages for the client's session are based on the file descriptor (or FILE * stream), (e.g., read(), lseek(), fgets()).
• The session is terminated (or “dissociated”) when the client closes the file descriptor or stream (or terminates for any reason).
• All client file-descriptor-based function calls are translated into messages.
