In addition we've added a number * of iprt specific format types for the iprt typedefs and other useful stuff. * Note that several of these are similar to \%p and doesn't care much if you try * add formating flags/width/precision. * * * Group 1, the basic runtime typedefs (excluding those which obviously are pointer). * - \%RTbool - Takes a bool value and prints 'true', 'false', or '!%d!'. * - \%RTfile - Takes a #RTFILE value. * - \%RTfmode - Takes a #RTFMODE value. * - \%RTfoff - Takes a #RTFOFF value. * - \%RTfp16 - Takes a #RTFAR16 value. * - \%RTfp32 - Takes a #RTFAR32 value. * - \%RTfp64 - Takes a #RTFAR64 value. * - \%RTgid - Takes a #RTGID value. * - \%RTino - Takes a #RTINODE value. * - \%RTint - Takes a #RTINT value. * - \%RTiop - Takes a #RTIOPORT value. * - \%RTldrm - Takes a #RTLDRMOD value. * - \%RTnthrd - Takes a #RTNATIVETHREAD value. * - \%RTproc - Takes a #RTPROCESS value. * - \%RTptr - Takes a #RTINTPTR or #RTUINTPTR value (but not void *). * - \%RTreg - Takes a #RTUINTREG value. * - \%RTsel - Takes a #RTSEL value. * - \%RTsem - Takes a #RTSEMEVENT, #RTSEMEVENTMULTI, #RTSEMMUTEX, #RTSEMFASTMUTEX, or #RTSEMRW value. * - \%RTsock - Takes a #RTSOCKET value. * - \%RTthrd - Takes a #RTTHREAD value. * - \%RTuid - Takes a #RTUID value. * - \%RTuint - Takes a #RTUINT value. * - \%RTunicp - Takes a #RTUNICP value. * - \%RTutf16 - Takes a #RTUTF16 value. * - \%RTuuid - Takes a #PCRTUUID and will print the UUID as a string. * - \%RTxuint - Takes a #RTUINT or #RTINT value, formatting it as hex. * - \%RGi - Takes a #RTGCINT value. * - \%RGp - Takes a #RTGCPHYS value. * - \%RGr - Takes a #RTGCUINTREG value. * - \%RGu - Takes a #RTGCUINT value. * - \%RGv - Takes a #RTGCPTR, #RTGCINTPTR or #RTGCUINTPTR value. * - \%RGx - Takes a #RTGCUINT or #RTGCINT value, formatting it as hex. * - \%RHi - Takes a #RTHCINT value. * - \%RHp - Takes a #RTHCPHYS value. * - \%RHr - Takes a #RTHCUINTREG value. * - \%RHu - Takes a #RTHCUINT value. * - \%RHv - Takes a #RTHCPTR, #RTHCINTPTR or #RTHCUINTPTR value. * - \%RHx - Takes a #RTHCUINT or #RTHCINT value, formatting it as hex. * - \%RCi - Takes a #RTCCINT value. * - \%RCp - Takes a #RTCCPHYS value. * - \%RCr - Takes a #RTCCUINTREG value. * - \%RCu - Takes a #RTUINT value. * - \%RCv - Takes a #uintptr_t, #intptr_t, void * value. * - \%RCx - Takes a #RTUINT or #RTINT value, formatting it as hex. * * * Group 2, the generic integer types which are prefered over relying on what * bit-count a 'long', 'short', or 'long long' has on a platform. This are * highly prefered for the [u]intXX_t kind of types. * - \%RI[8|16|32|64] - Signed integer value of the specifed bit count. * - \%RU[8|16|32|64] - Unsigned integer value of the specifed bit count. * - \%RX[8|16|32|64] - Hexadecimal integer value of the specifed bit count. * * * Group 3, hex dumpers and other complex stuff which requires more than simple formatting. * - \%Rhxd - Takes a pointer to the memory which is to be dumped in typical * hex format. Use the width to specify the length, and the precision to * set the number of bytes per line. Default width and precision is 16. * - \%Rhxs - Takes a pointer to the memory to be displayed as a hex string, * i.e. a series of space separated bytes formatted as two digit hex value. * Use the width to specify the length. Default length is 16 bytes. * - \%Rrc - Takes an integer iprt status code as argument. Will insert the * status code define corresponding to the iprt status code. * - \%Rrs - Takes an integer iprt status code as argument. Will insert the * short description of the specified status code. * - \%Rrf - Takes an integer iprt status code as argument. Will insert the * full description of the specified status code. * - \%Rra - Takes an integer iprt status code as argument. Will insert the * status code define + full description. * - \%Rt - Current thread (RTThreadSelf()), no arguments. * * - \%Rwc - Takes a long Windows error code as argument. Will insert the status * code define corresponding to the Windows error code. * - \%Rwf - Takes a long Windows error code as argument. Will insert the * full description of the specified status code. * - \%Rwa - Takes a long Windows error code as argument. Will insert the * error code define + full description. * * On other platforms, \%Rw? simply prints the argument in a form of 0xXXXXXXXX. * * @todo (r=dmik) Add a cross-platform \%Rcomr? that will fall back to \%Rw? on * Win32 platforms and will interpret XPCOM result codes on all other. * * * Group 4, structure dumpers. * * - \%RDtimespec - Takes a PCRTTIMESPEC. * * */ /******************************************************************************* * Header Files * *******************************************************************************/ #define LOG_GROUP RTLOGGROUP_STRING #include #include #include #include #include #ifdef IN_RING3 # include # include #endif #include #include "internal/string.h" /** * Callback to format iprt formatting extentions. * See @ref pg_rt_str_format_rt for a reference on the format types. * * @returns The number of bytes formatted. * @param pfnOutput Pointer to output function. * @param pvArgOutput Argument for the output function. * @param ppszFormat Pointer to the format string pointer.
