--------------------------------------------------
CONSTANT:
``CONFIGURE_MINIMUM_TASKS_WITH_USER_PROVIDED_STORAGE``
OPTION TYPE:
This configuration option is an integer define.
DEFAULT VALUE:
The default value is 0.
VALUE CONSTRAINTS:
The value of this configuration option shall be greater than or equal to 0
and less than or equal to :ref:`CONFIGURE_MAXIMUM_TASKS`.
DESCRIPTION:
The value of this configuration option defines the minimum count of Classic
API Tasks which are constructed by :c:func:`rtems_task_construct`.
NOTES:
By default, the calculation for the required memory in the RTEMS Workspace
for tasks assumes that all Classic API Tasks are created by
:c:func:`rtems_task_create`. This configuration option can be used to
reduce the required memory for the system-provided task storage areas since
tasks constructed by :c:func:`rtems_task_construct` use a user-provided
task storage area.
