* We have three pre-defined constructor priorities:
|
*
|
* - One for setup calls (__setup_ctor), which are guaranteed to run
|
* prior to the bootstrap code. You should use setup calls for
|
* implementing initialization hooks which depend on a particular call
|
* order. Each Xenomai interface layer is initialized via a dedicated
|
* setup call.
|
*
|
* - A second priority is assigned to early init calls (__early_ctor),
|
* which are also guaranteed to run prior to the bootstrap
|
* code. Whether such early code runs before OR after any setup code
|
* is __UNSPECIFIED__. By design, such code may not invoke any Xenomai
|
* service, and generally speaking, should have no dependencies on
|
* anything else.
|
*
|
* - The last priority level is used for the bootstrap code
|
* (__bootstrap_ctor), which is guaranteed to run after any
|
* setup/early code, provided such bootstrap code is part of the main
|
* executable.
|
*
|
* The guarantees on the init order don't go beyond what is stated
|
* here, do NOT assume more than this.
