31	/** @page pg_rt_str_format_rt The IPRT String Format Extensions
32	*
33	* The string formatter supports most of the non-float format types and flags.
34	* See RTStrFormatV() for the full tail there. In addition we've added a number
35	* of iprt specific format types for the iprt typedefs and other useful stuff.
36	* Note that several of these are similar to \%p and doesn't care much if you try
37	* add formating flags/width/precision.
38	*
39	*
40	* Group 1, the basic runtime typedefs (excluding those which obviously are pointer).
41	* - \%RTbool - Takes a bool value and prints 'true', 'false', or '!%d!'.
42	* - \%RTfile - Takes a #RTFILE value.
43	* - \%RTfmode - Takes a #RTFMODE value.
44	* - \%RTfoff - Takes a #RTFOFF value.
45	* - \%RTfp16 - Takes a #RTFAR16 value.
46	* - \%RTfp32 - Takes a #RTFAR32 value.
47	* - \%RTfp64 - Takes a #RTFAR64 value.
48	* - \%RTgid - Takes a #RTGID value.
49	* - \%RTino - Takes a #RTINODE value.
50	* - \%RTint - Takes a #RTINT value.
51	* - \%RTiop - Takes a #RTIOPORT value.
52	* - \%RTldrm - Takes a #RTLDRMOD value.
53	* - \%RTnthrd - Takes a #RTNATIVETHREAD value.
54	* - \%RTproc - Takes a #RTPROCESS value.
55	* - \%RTptr - Takes a #RTINTPTR or #RTUINTPTR value (but not void *).
56	* - \%RTreg - Takes a #RTCCUINTREG value.
57	* - \%RTsel - Takes a #RTSEL value.
58	* - \%RTsem - Takes a #RTSEMEVENT, #RTSEMEVENTMULTI, #RTSEMMUTEX, #RTSEMFASTMUTEX, or #RTSEMRW value.
59	* - \%RTsock - Takes a #RTSOCKET value.
60	* - \%RTthrd - Takes a #RTTHREAD value.
61	* - \%RTuid - Takes a #RTUID value.
62	* - \%RTuint - Takes a #RTUINT value.
63	* - \%RTunicp - Takes a #RTUNICP value.
64	* - \%RTutf16 - Takes a #RTUTF16 value.
65	* - \%RTuuid - Takes a #PCRTUUID and will print the UUID as a string.
66	* - \%RTxuint - Takes a #RTUINT or #RTINT value, formatting it as hex.
67	* - \%RGi - Takes a #RTGCINT value.
68	* - \%RGp - Takes a #RTGCPHYS value.
69	* - \%RGr - Takes a #RTGCUINTREG value.
70	* - \%RGu - Takes a #RTGCUINT value.
71	* - \%RGv - Takes a #RTGCPTR, #RTGCINTPTR or #RTGCUINTPTR value.
72	* - \%RGx - Takes a #RTGCUINT or #RTGCINT value, formatting it as hex.
73	* - \%RHi - Takes a #RTHCINT value.
74	* - \%RHp - Takes a #RTHCPHYS value.
75	* - \%RHr - Takes a #RTHCUINTREG value.
76	* - \%RHu - Takes a #RTHCUINT value.
77	* - \%RHv - Takes a #RTHCPTR, #RTHCINTPTR or #RTHCUINTPTR value.
78	* - \%RHx - Takes a #RTHCUINT or #RTHCINT value, formatting it as hex.
79	* - \%RRv - Takes a #RTRCPTR, #RTRCINTPTR or #RTRCUINTPTR value.
80	* - \%RCi - Takes a #RTCCINT value.
81	* - \%RCp - Takes a #RTCCPHYS value.
82	* - \%RCr - Takes a #RTCCUINTREG value.
83	* - \%RCu - Takes a #RTUINT value.
84	* - \%RCv - Takes a #uintptr_t, #intptr_t, void * value.
85	* - \%RCx - Takes a #RTUINT or #RTINT value, formatting it as hex.
86	*
87	*
88	* Group 2, the generic integer types which are prefered over relying on what
89	* bit-count a 'long', 'short', or 'long long' has on a platform. This are
90	* highly prefered for the [u]intXX_t kind of types.
91	* - \%RI[8\|16\|32\|64] - Signed integer value of the specifed bit count.
92	* - \%RU[8\|16\|32\|64] - Unsigned integer value of the specifed bit count.
93	* - \%RX[8\|16\|32\|64] - Hexadecimal integer value of the specifed bit count.
94	*
95	*
96	* Group 3, hex dumpers and other complex stuff which requires more than simple formatting.
97	* - \%Rhxd - Takes a pointer to the memory which is to be dumped in typical
98	* hex format. Use the width to specify the length, and the precision to
99	* set the number of bytes per line. Default width and precision is 16.
100	* - \%Rhxs - Takes a pointer to the memory to be displayed as a hex string,
101	* i.e. a series of space separated bytes formatted as two digit hex value.
102	* Use the width to specify the length. Default length is 16 bytes.
103	* - \%Rrc - Takes an integer iprt status code as argument. Will insert the
104	* status code define corresponding to the iprt status code.
105	* - \%Rrs - Takes an integer iprt status code as argument. Will insert the
106	* short description of the specified status code.
107	* - \%Rrf - Takes an integer iprt status code as argument. Will insert the
108	* full description of the specified status code.
109	* - \%Rra - Takes an integer iprt status code as argument. Will insert the
110	* status code define + full description.
111	* - \%Rt - Current thread (RTThreadSelf()), no arguments.
112	*
113	* - \%Rwc - Takes a long Windows error code as argument. Will insert the status
114	* code define corresponding to the Windows error code.
115	* - \%Rwf - Takes a long Windows error code as argument. Will insert the
116	* full description of the specified status code.
117	* - \%Rwa - Takes a long Windows error code as argument. Will insert the
118	* error code define + full description.
119	*
120	* - \%Rhrc - Takes a COM/XPCOM status code as argument. Will insert the status
121	* code define corresponding to the Windows error code.
122	* - \%Rhrf - Takes a COM/XPCOM status code as argument. Will insert the
123	* full description of the specified status code.
124	* - \%Rhra - Takes a COM/XPCOM error code as argument. Will insert the
125	* error code define + full description.
126	*
127	* - \%Rfn - Pretty printing of a function or method. It drops the
128	* return code and parameter list.
129	*
130	* On other platforms, \%Rw? simply prints the argument in a form of 0xXXXXXXXX.
131	*
132	*
133	* Group 4, structure dumpers.
134	*
135	* - \%RDtimespec - Takes a PCRTTIMESPEC.
