CONFIG_MINIMAL_LIBC_RAND

Enables rand and srand functions

Type: bool

Help

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

(Includes any dependencies from ifs and menus.)

Defaults
