◆ defer

#define defer ( n )

Value:

    quicr::ScopeGuard QUICR_DEFER_CONCAT(defer_, __LINE__)([&]() {                                                     \
        QUICR_DEFER_PUSH n;                                                                                            \
        QUICR_DEFER_POP                                                                                                \
    })

Runs statements when the current scope exits.

Parameters

n	Statements captured by reference and executed exactly once by a generated scope guard.

Warning: Every referenced object must outlive the generated guard. An exception escaping n during stack unwinding terminates the process because the guard destructor is noexcept.

◆ QUICR_DEFER_CONCAT

#define QUICR_DEFER_CONCAT	(	a,
		b
	)	QUICR_DEFER_CONCAT_INNER(a, b)

◆ QUICR_DEFER_CONCAT_INNER

#define QUICR_DEFER_CONCAT_INNER	(	a,
		b
	)	a##b

Concatenates two preprocessing tokens after outer expansion.

◆ QUICR_DEFER_POP

#define QUICR_DEFER_POP

No-op on compilers that do not require deferred-action diagnostic suppression.
