This configuration option is an initializer define.

The default value is ``POSIX_Init``.
|
|
|
|

|
The value of this configuration option initializes the entry point of the
|
|
POSIX API initialization thread.

The application shall provide the function referenced by this configuration
|

option.
|

|
|
|
|
The value of the configuration option shall be defined to a valid function
|
|
pointer of the type ``void *( *entry_point )( void * )``.

This configuration option is an integer define.

The default value is :ref:`CONFIGURE_MINIMUM_POSIX_THREAD_STACK_SIZE`.

|
|
|
|
The value of this configuration option defines the thread stack size of the
|
|
POSIX API initialization thread.
|
|
|
|
.. rubric:: CONSTRAINTS:
|
|
|
|
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>`_.

This configuration option is a boolean feature define.
|
|
|
|
.. rubric:: DEFAULT CONFIGURATION:
|
|
|
|
If this configuration option is undefined, then the described feature is not
|
|
enabled.
|
|
|
|
.. rubric:: DESCRIPTION:
|
|
|
|
In case this configuration option is defined, then exactly one POSIX
|
|
initialization thread is configured.
|
|
|
|
.. rubric:: NOTES:
|
|
|
|
The application shall define at least 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.
|
|
|
|
If no Classic API initialization task is configured, then the POSIX API
|
|
initialization thread performs the :ref:`GlobalConstruction`.
