Callback init()

It is called very early while initializing the framework.

• parameter you get
  • framework handle
  • a pointer to your own private data (on demand via caps_drv_run(), for configuation options for example)

    Attention

    This pointer differs from the pointer of all other callback functions.

• you can expect as already done
  • command line arguments are already processed (but its up to you when you call caps_arg_parser_process())
  • nothing else. This is really internal only.
• what you can do
  • you can allocate your private memory and register it as a hint for the other callbacks via caps_drv_private_set()
• what you must do
  • nothing
• values you should return
  • 0 everything is okay, the framework can continue
  • -EINVAL Something really bad happened in your initialisation and the framework should terminate

Note

This callback is optional.
