CONFIG_MINIMAL_LIBC_RAND
########################

*Enables rand and srand functions*

Type: ``bool``

Help
====

.. code-block:: none

    Enable rand() and srand() for the minimal libc. The
    functions implicitly access global/static data.  Such data
    must be put into a memory partition if CONFIG_USERSPACE=y,
    and disabling this option may save an entry for application
    defining many custom partitions.

    Say 'Y' here if you need rand() and srand(). This might require
    an additional memory partition.

Direct dependencies
