Macro Definition Documentation

#define VCSN_REQUIRE	(		Cond,
			...
	)

Value:

do {                                          \
    if (!(Cond))                                \
      ::vcsn::raise(__VA_ARGS__);               \
  } while (false)

A macro similar to require.

Its point is to avoid the cost of the evaluation of the variadic arguments.
