Clear the page for each configuration options similar to the directives. Use a rubric instead of a definition list for the application configuration options similar to the directive documentation pages. For direcives and application configuration options use the same rubric order. Generalize value constraints to constraints. This patch does not change hand written content.

|
|
|
|
The following constraints apply to this configuration option:
|
|
|
|
* The value of the configuration option shall be greater than or equal to
|
|
:ref:`CONFIGURE_MINIMUM_TASK_STACK_SIZE`.
|
|
|
|
* The value of the configuration option shall be small enough so that the task
|
|
stack space calculation carried out by ``<rtems/confdefs.h>`` does not
|
|
overflow an integer of type `uintptr_t
|
|
<https://en.cppreference.com/w/c/types/integer>`_.

|
|
|
|
In case this configuration option is defined, then exactly one POSIX

initialization thread is configured.

.. rubric:: NOTES:
|
|
|
|
The application shall define exactly one of the following configuration

options
|
