#define FOLLY_SAFE_CHECK_IMPL	(		expr,
			expr_s,
			msg
	)

Value:

((expr) ? static_cast<void>(0)                 \
          : ::folly::detail::assertionFailure(   \
                FB_STRINGIZE(expr_s),            \
                (msg),                           \
                __FILE__,                        \
                __LINE__,                        \
                __PRETTY_FUNCTION__))

Verify that the expression is true. If not, prints an error message (containing msg) to stderr and abort()s. Just like CHECK(), but only logs to stderr and only does async-signal-safe calls.

#define FOLLY_SAFE_DCHECK	(		expr,
			msg
	)		FOLLY_SAFE_CHECK_IMPL(!folly::kIsDebug || (expr), (expr), (msg))

In debug mode, verify that the expression is true. Otherwise, do nothing (do not even evaluate expr). Just like DCHECK(), but only logs to stderr and only does async-signal-safe calls.
