CRYPT_EAL_MacUpdate() int32_t CRYPT_EAL_MacUpdate ( CRYPT_EAL_MacCtx *  ctx, const uint8_t *  in, uint32_t  len  ) Continuously input the MAC data. This command is used only after the CRYPT_EAL_MacInit interface is successfully called. 参数 ctx [IN] MAC context in [IN] Input data, when the variable is null, the len parameter must be 0. Otherwise, an error is reported. len [IN] Input data length, the value can be 0. 返回值 CRYPT_SUCCESS,succeeded in updating the internal status of the digest. CRYPT_NULL_INPUT,the input parameter is NULL. CRYPT_EAL_ERR_STATE,status error. CRYPT_SHA1_INPUT_OVERFLOW,the length of the HMAC-SHA1 input data exceeds the maximum value. CRYPT_SHA2_INPUT_OVERFLOW,the length of the HMAC-SHA224, HMAC-SHA256, HMAC-SHA384, or HMAC-SHA512 input data exceeds the maximum value, Other error codes see the crypt_errno.h.
