Typedef Documentation

typedef enum rng_return rng_return_t

Return values (error codes) for kernel register interface functions

typedef struct rng_work_entry rng_work_entry_t

An entry in the RNG Work Queue. Based upon standard SHW queue entry.

This entry also gets saved (for non-blocking requests) in the user's result pool. When the user picks up the request, the final processing (copy from data_local to data_user) will get made if status was good.
