POSIX Initialization Thread Configuration
=========================================
This section describes configuration options related to the POSIX
initialization thread.
.. Generated from spec:/acfg/if/posix-init-thread-entry-point
.. 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.
.. Generated from spec:/acfg/if/posix-init-thread-stack-size
.. 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.
.. Generated from spec:/acfg/if/posix-init-thread-table
.. 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.
