#define BREAK_ON_EPID_ERROR

(

ret

)

Value:

if (kEpidNoErr != (ret)) {     \
    break;                       \
  }

Handle SDK Error with Break.

#define BREAK_ON_IPP_ERROR	(		sts,
			ret
	)

Value:

{                                            \
    IppStatus temp_sts = (sts);                \

    }                                          \
  }

Handle Ipp Errors with Break.

#define RETURN_ON_IPP_ERROR

(

sts

)

Value:
