NAME

       kcapi_rng_init - initialize cipher handle

SYNOPSIS

       int kcapi_rng_init(struct kcapi_handle ** handle, const char * ciphername,
                          uint32_t flags);

ARGUMENTS

       handle
           [out] cipher handle filled during the call

       ciphername
           [in] kernel crypto API cipher name as specified in /proc/crypto

       flags
           [in] flags specifying the type of cipher handle (unused for RNG)

DESCRIPTION

       This function provides the initialization of a random number generator handle and
       establishes the connection to the kernel.

       On success, a pointer to kcapi_handle object is returned in *handle. Function
       kcapi_rng_destroy should be called afterwards to free resources.

       return 0 upon success; -ENOENT - algorithm not available; -EOPNOTSUPP - AF_ALG family not
       available; -EINVAL - accept syscall failed -ENOMEM - cipher handle cannot be allocated
