#define ut_a

(

EXPR

)

Value:

do {                                            \
        if (UT_DBG_FAIL(EXPR)) {                                \
                ut_dbg_assertion_failed(#EXPR,                  \
                                __FILE__, (ulint) __LINE__);    \
                UT_DBG_PANIC;                                   \
        }                                                       \
} while (0)

Abort execution if EXPR does not evaluate to nonzero.

Parameters

EXPR	assertion expression that should hold
