/*
|
|
* The basic principle of operation is:
|
|
* No asynchronous behavior, no indeterminism.
|
|
* If you run the same thing 20 times, you get exactly the same result 20
|
|
* times.
|
|
* It does not matter if you are running from console, or in a debugger
|
|
* and you go for lunch in the middle of the debug session.
|
|
*
|
|
* This is achieved as follows:
|
|
* The execution of native_posix is decoupled from the underlying host and its
|
|
* peripherals (unless set otherwise).
|
|
* In general, time in native_posix is simulated.
|
|
*
|
|
* But, native_posix can also be linked if desired to the underlying host,
|
|
* e.g.:You can use the provided Ethernet TAP driver, or a host BLE controller.
|
|
*
|
|
* In this case, the no-indeterminism principle is lost. Runs of native_posix
|
|
* will depend on the host load and the interactions with those real host
|
|
* peripherals.
