Subject: using compile-time "assertions"
Date: Sun, 5 Jun 2005 16:36:34 -0400 (EDT) [thread overview]
Message-ID: <Pine.LNX.4.61.0506051632530.5573@localhost.localdomain> (raw)
another question (one of undoubtedly many) regarding the code i
inherited. in this code, there is liberal use of the following macro:
#define INVARIANT(e) \
do { \
struct whatever { char static_assertion[(e) ? 1 : -1]; }; \
} while (0)
which i recognize as a *compile-time* assertion/invariant. is this a
common construct? just curious. or is there a more popular variant
of this sort of thing? i recognize its value but, geez, there's
hundreds of these things in the code. :-P
