DESCRIPTION
|
|
This header file declares prototypes for the kernel's random number generator
|
|
APIs.
|
|
|
|
Typically a BSP should enable the hidden CUSTOM_RANDOM_GENERATOR configuration
|
|
option and provide its the implementations for sys_rand32_init() and
|
|
sys_rand32_get().
|
|
However, if it does not do so a project requiring random numbers must implement
|
|
these routines, or (for testing purposes only) enable the TEST_RANDOM_GENERATOR
|
|
configuration option.
