If only one constraint is present, then use a single sentence, otherwise use a list for the constraints. Format the constraints so that the line length limit is maintained.

This section describes configuration options related to the POSIX
|
|
initialization thread.

CONSTANT:

|
``CONFIGURE_POSIX_INIT_THREAD_ENTRY_POINT``
|
|
|
|
OPTION TYPE:
|
|
This configuration option is an initializer define.
|
|
|
|
DEFAULT VALUE:
|
|
The default value is ``POSIX_Init``.
|
|
|
|
VALUE CONSTRAINTS:
|
|
The value of this configuration option shall be defined to a valid function
|
|
pointer of the type ``void *( *entry_point )( void * )``.
|
|
|
|
DESCRIPTION:
|
|
The value of this configuration option initializes the entry point of the
|
|
POSIX API initialization thread.
|
|
|
|
NOTES:
|
|
The application shall provide the function referenced by this configuration
|
|
option.

|
|
|
|
OPTION TYPE:
|
|
This configuration option is an integer define.
|
|
|
|
DEFAULT VALUE:
|
|
The default value is :ref:`CONFIGURE_MINIMUM_POSIX_THREAD_STACK_SIZE`.
|
|
|
|
VALUE CONSTRAINTS:
|
|
The value of this configuration option shall satisfy all of the following
|
|
constraints:
|
|
|
|
* It shall be greater than or equal to
|
|
:ref:`CONFIGURE_MINIMUM_TASK_STACK_SIZE`.
|
|
|
|
* It 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>`_.
|
|
|
|
DESCRIPTION:
|
|
The value of this configuration option defines the thread stack size of the
|
|
POSIX API initialization thread.
|
|
|
|
NOTES:
|
|
None.

|
|
DEFAULT CONFIGURATION:
|
|
If this configuration option is undefined, then the described feature is not
|
|
enabled.
|
|
|
|
DESCRIPTION:
|
|
In case this configuration option is defined, then exactly one POSIX
|
|
initialization thread is configured.
|
|
|
|
NOTES:
|
|
The application shall define exactly one of the following configuration
|
|
options
|
|
|
|
* :ref:`CONFIGURE_RTEMS_INIT_TASKS_TABLE`,
|
|
|
|
* ``CONFIGURE_POSIX_INIT_THREAD_TABLE``, or
|
|
|
|
* :ref:`CONFIGURE_IDLE_TASK_INITIALIZES_APPLICATION`
|
|
|
|
otherwise a compile time error in the configuration file will occur.
