POSIX Initialization Thread Configuration
=========================================

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

.. index:: CONFIGURE_POSIX_INIT_THREAD_ENTRY_POINT

.. _CONFIGURE_POSIX_INIT_THREAD_ENTRY_POINT:

CONFIGURE_POSIX_INIT_THREAD_ENTRY_POINT
---------------------------------------

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.

.. index:: CONFIGURE_POSIX_INIT_THREAD_STACK_SIZE

.. _CONFIGURE_POSIX_INIT_THREAD_STACK_SIZE:

CONFIGURE_POSIX_INIT_THREAD_STACK_SIZE
--------------------------------------

CONSTANT:
    ``CONFIGURE_POSIX_INIT_THREAD_STACK_SIZE``

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.

.. index:: CONFIGURE_POSIX_INIT_THREAD_TABLE

.. _CONFIGURE_POSIX_INIT_THREAD_TABLE:

CONFIGURE_POSIX_INIT_THREAD_TABLE
---------------------------------

CONSTANT:
    ``CONFIGURE_POSIX_INIT_THREAD_TABLE``

OPTION TYPE:
    This configuration option is a boolean feature define.

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.
