CRYPT_EAL_Drbgbytes() int32_t CRYPT_EAL_Drbgbytes ( CRYPT_EAL_RndCtx *  ctx, uint8_t *  byte, uint32_t  len  ) Generate a random number, which is equivalent to CRYPT_EAL_RandbytesWithAdin(bytes, len, NULL, 0). This interface supports multi-thread access. 参数 ctx [IN] DRBG handle byte [OUT] Used to store output random numbers. the memory is provided by the user. len [IN] Required random number length. the range is (0, 65536]. 返回值 CRYPT_SUCCESS,if successful. For other error codes, see the crypt_errno.h file.
