Client summary

QNX SDP8.0Getting Started with the QNX OSDeveloperUser

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.
