34	* @ingroup grp_rt
35	*
36	* Assertions are generally used to check preconditions and other
37	* assumptions. Sometimes it is also used to catch odd errors or errors
38	* that one would like to inspect in the debugger. They should not be
39	* used for errors that happen frequently.
40	*
41	* IPRT provides a host of assertion macros, so many that it can be a bit
42	* overwhelming at first. Don't despair, there is a system (surprise).
43	*
44	* First there are four families of assertions:
45	* - Assert - The normal strict build only assertions.
46	* - AssertLogRel - Calls LogRel() in non-strict builds, otherwise like Assert.
47	* - AssertRelease - Triggers in all builds.
48	* - AssertFatal - Triggers in all builds and cannot be continued.
49	*
50	* Then there are variations wrt to argument list and behavior on failure:
51	* - Msg - Custom RTStrPrintf-like message with the assertion message.
52	* - Return - Return the specific rc on failure.
53	* - ReturnVoid - Return (void) on failure.
54	* - Break - Break (out of switch/loop) on failure.
55	* - Stmt - Execute the specified statement(s) on failure.
56	* - RC - Assert RT_SUCCESS.
57	* - RCSuccess - Assert VINF_SUCCESS.
58	*
59	* In addition there is a very special family AssertCompile that can be
60	* used for some limited compile-time checking, like structure sizes and member
61	* alignment. This family doesn't have the same variations.
62	*
63	*
64	* @remarks As you might have noticed, the macros don't follow the
65	* coding guidelines wrt to macros supposedly being all uppercase
66	* and underscored. For various reasons they don't, and nobody
67	* has complained yet. Wonder why... :-)
68	*
69	* @remarks Each project has its own specific guidelines on how to use
70	* assertions, so the above is just trying to give you the general idea
71	* from the IPRT point of view.
