//  FILE:  StdString.h\r
//  AUTHOR:     Joe O'Leary (with outside help noted in comments)\r
//  REMARKS:\r
//              This header file declares the CStdStr template.  This template derives\r
//              the Standard C++ Library basic_string<> template and add to it the\r
//              the following conveniences:\r
//                      - The full MFC CString set of functions (including implicit cast)\r
//                      - writing to/reading from COM IStream interfaces\r
//                      - Functional objects for use in STL algorithms\r
//\r
//              From this template, we intstantiate two classes:  CStdStringA and\r
//              CStdStringW.  The name "CStdString" is just a #define of one of these,\r
//              based upone the _UNICODE macro setting\r
//\r
//              This header also declares our own version of the MFC/ATL UNICODE-MBCS\r
//              conversion macros.  Our version looks exactly like the Microsoft's to\r
//              facilitate portability.\r
//\r
//      NOTE:\r
//              If you you use this in an MFC or ATL build, you should include either\r
//              afx.h or atlbase.h first, as appropriate.\r
//\r
//      PEOPLE WHO HAVE CONTRIBUTED TO THIS CLASS:\r
//\r
//              Several people have helped me iron out problems and othewise improve\r
//              this class.  OK, this is a long list but in my own defense, this code\r
//              has undergone two major rewrites.  Many of the improvements became\r
//              necessary after I rewrote the code as a template.  Others helped me\r
//              improve the CString facade.\r
//\r
//              Anyway, these people are (in chronological order):\r

//      REVISION HISTORY\r
//    2003-JUL-10 - Thanks to Charles G for making me realize my 'FmtArg' fixes\r
//                  had inadvertently broken the DLL-export code (which is\r
//                  normally commented out.  I had to move it up higher.  Also\r
//                                      this helped me catch a bug in ssicoll that would prevent\r
//                  compilation, otherwise.\r
//\r
//    2003-MAR-14 - Thanks to Jakko Van Hunen for pointing out a copy-and-paste\r
//                  bug in one of the overloads of FmtArg.\r
//\r
//    2003-MAR-10 - Thanks to Ronny Schulz for (twice!) sending me some changes\r
//                  to help CStdString build on SGI and for pointing out an\r
//                  error in placement of my preprocessor macros for ssfmtmsg.\r
//\r
//    2002-NOV-26 - Thanks to Bagira for pointing out that my implementation of\r
//                  SpanExcluding was not properly handling the case in which\r
//                  the string did NOT contain any of the given characters\r
//\r
//    2002-OCT-21 - Many thanks to Paul DeMarco who was invaluable in helping me\r
//                  get this code working with Borland's free compiler as well\r
//                  as the Dev-C++ compiler (available free at SourceForge).\r
//\r
//    2002-SEP-13 - Thanks to Glen Maynard who helped me get rid of some loud\r
//                  but harmless warnings that were showing up on g++.  Glen\r
//                  also pointed out that some pre-declarations of FmtArg<>\r
//                  specializations were unnecessary (and no good on G++)\r
//\r
//    2002-JUN-26 - Thanks to Arnt Witteveen for pointing out that I was using\r
//                  static_cast<> in a place in which I should have been using\r
//                  reinterpret_cast<> (the ctor for unsigned char strings).\r
//                  That's what happens when I don't unit-test properly!\r
//                  Arnt also noticed that CString was silently correcting the\r
//                  'nCount' argument to Left() and Right() where CStdString was\r
//                  not (and crashing if it was bad).  That is also now fixed!\r
//\r
//        2002-FEB-25 - Thanks to Tim Dowty for pointing out (and giving me the fix\r
//                                      for) a conversion problem with non-ASCII MBCS characters.\r
//                                      CStdString is now used in my favorite commercial MP3 player!\r
//\r
//        2001-DEC-06 - Thanks to Wang Haifeng for spotting a problem in one of the\r
//                                      assignment operators (for _bstr_t) that would cause compiler\r
//                                      errors when refcounting protection was turned off.\r
//\r
//        2001-NOV-27 - Remove calls to operator!= which involve reverse_iterators\r
//                                      due to a conflict with the rel_ops operator!=.  Thanks to\r
//                                      John James for pointing this out.\r
//\r
//    2001-OCT-29 - Added a minor range checking fix for the Mid function to\r
//                                      make it as forgiving as CString's version is.  Thanks to\r
//                                      Igor Kholodov for noticing this.  \r
//                                - Added a specialization of std::swap for CStdString.  Thanks\r
//                                      to Mike Crusader for suggesting this!  It's commented out\r
//                                      because you're not supposed to inject your own code into the\r
//                                      'std' namespace.  But if you don't care about that, it's\r
//                                      there if you want it\r
//                                - Thanks to Jason Mills for catching a case where CString was\r
//                                      more forgiving in the Delete() function than I was.\r
//\r
//        2001-JUN-06 - I was violating the Standard name lookup rules stated\r
//                                      in [14.6.2(3)].  None of the compilers I've tried so\r
//                                      far apparently caught this but HP-UX aCC 3.30 did.  The\r
//                                      fix was to add 'this->' prefixes in many places.\r
//                                      Thanks to Farrokh Nejadlotfi for this!\r
//\r
//        2001-APR-27 - StreamLoad was calculating the number of BYTES in one\r
//                                      case, not characters.  Thanks to Pablo Presedo for this.\r
//\r
//    2001-FEB-23 - Replace() had a bug which caused infinite loops if the\r
//                                      source string was empty.  Fixed thanks to Eric Nitzsche.\r
//\r
//    2001-FEB-23 - Scott Hathaway was a huge help in providing me with the\r
//                                      ability to build CStdString on Sun Unix systems.  He\r
//                                      sent me detailed build reports about what works and what\r
//                                      does not.  If CStdString compiles on your Unix box, you\r
//                                      can thank Scott for it.\r
//\r
//        2000-DEC-29 - Joldakowski noticed one overload of Insert failed to do a\r
//                                      range check as CString's does.  Now fixed -- thanks!\r
//\r
//        2000-NOV-07 - Aaron pointed out that I was calling static member\r
//                                      functions of char_traits via a temporary.  This was not\r
//                                      technically wrong, but it was unnecessary and caused\r
//                                      problems for poor old buggy VC5.  Thanks Aaron!\r
//\r
//        2000-JUL-11 - Joe Woodbury noted that the CString::Find docs don't match\r
//                                      what the CString::Find code really ends up doing.   I was\r
//                                      trying to match the docs.  Now I match the CString code\r
//                                - Joe also caught me truncating strings for GetBuffer() calls\r
//                                      when the supplied length was less than the current length.\r
//\r
//        2000-MAY-25 - Better support for STLPORT's Standard library distribution\r
//                                - Got rid of the NSP macro - it interfered with Koenig lookup\r
//                                - Thanks to Joe Woodbury for catching a TrimLeft() bug that\r
//                                      I introduced in January.  Empty strings were not getting\r
//                                      trimmed\r
//\r
//        2000-APR-17 - Thanks to Joe Vitaterna for pointing out that ReverseFind\r
//                                      is supposed to be a const function.\r
//\r
//        2000-MAR-07 - Thanks to Ullrich Pollähne for catching a range bug in one\r
//                                      of the overloads of assign.\r
//\r
//    2000-FEB-01 - You can now use CStdString on the Mac with CodeWarrior!\r
//                                      Thanks to Todd Heckel for helping out with this.\r
//\r
//        2000-JAN-23 - Thanks to Jim Cline for pointing out how I could make the\r
//                                      Trim() function more efficient.\r
//                                - Thanks to Jeff Kohn for prompting me to find and fix a typo\r
//                                      in one of the addition operators that takes _bstr_t.\r
//                                - Got rid of the .CPP file -  you only need StdString.h now!\r
//\r
//        1999-DEC-22 - Thanks to Greg Pickles for helping me identify a problem\r
//                                      with my implementation of CStdString::FormatV in which\r
//                                      resulting string might not be properly NULL terminated.\r
//\r
//        1999-DEC-06 - Chris Conti pointed yet another basic_string<> assignment\r
//                                      bug that MS has not fixed.  CStdString did nothing to fix\r
//                                      it either but it does now!  The bug was: create a string\r
//                                      longer than 31 characters, get a pointer to it (via c_str())\r
//                                      and then assign that pointer to the original string object.\r
//                                      The resulting string would be empty.  Not with CStdString!\r
//\r
//        1999-OCT-06 - BufferSet was erasing the string even when it was merely\r
//                                      supposed to shrink it.  Fixed.  Thanks to Chris Conti.\r
//                                - Some of the Q172398 fixes were not checking for assignment-\r
//                                      to-self.  Fixed.  Thanks to Baptiste Lepilleur.\r
//\r
//        1999-AUG-20 - Improved Load() function to be more efficient by using \r
//                                      SizeOfResource().  Thanks to Rich Zuris for this.\r
//                                - Corrected resource ID constructor, again thanks to Rich.\r
//                                - Fixed a bug that occurred with UNICODE characters above\r
//                                      the first 255 ANSI ones.  Thanks to Craig Watson. \r
//                                - Added missing overloads of TrimLeft() and TrimRight().\r
//                                      Thanks to Karim Ratib for pointing them out\r
//\r
//        1999-JUL-21 - Made all calls to GetBuf() with no args check length first.\r
//\r
//        1999-JUL-10 - Improved MFC/ATL independence of conversion macros\r
//                                - Added SS_NO_REFCOUNT macro to allow you to disable any\r
//                                      reference-counting your basic_string<> impl. may do.\r
//                                - Improved ReleaseBuffer() to be as forgiving as CString.\r
//                                      Thanks for Fan Xia for helping me find this and to\r
//                                      Matthew Williams for pointing it out directly.\r
//\r
//        1999-JUL-06 - Thanks to Nigel Nunn for catching a very sneaky bug in\r
//                                      ToLower/ToUpper.  They should call GetBuf() instead of\r
//                                      data() in order to ensure the changed string buffer is not\r
//                                      reference-counted (in those implementations that refcount).\r
//\r
//        1999-JUL-01 - Added a true CString facade.  Now you can use CStdString as\r
//                                      a drop-in replacement for CString.  If you find this useful,\r
//                                      you can thank Chris Sells for finally convincing me to give\r
//                                      in and implement it.\r
//                                - Changed operators << and >> (for MFC CArchive) to serialize\r
//                                      EXACTLY as CString's do.  So now you can send a CString out\r
//                                      to a CArchive and later read it in as a CStdString.   I have\r
//                                      no idea why you would want to do this but you can. \r
//\r
//        1999-JUN-21 - Changed the CStdString class into the CStdStr template.\r
//                                - Fixed FormatV() to correctly decrement the loop counter.\r
//                                      This was harmless bug but a bug nevertheless.  Thanks to\r
//                                      Chris (of Melbsys) for pointing it out\r

// MACRO: SS_UNSIGNED\r
// ------------------\r
//      This macro causes the addition of a constructor and assignment operator\r
//      which take unsigned characters.  CString has such functions and in order\r
//      to provide maximum CString-compatability, this code needs them as well.\r
//      In practice you will likely never need these functions...\r

\r
// MACRO: SS_SAFE_FORMAT\r
// ---------------------\r
//      This macro provides limited compatability with a questionable CString\r
//      "feature".  You can define it in order to avoid a common problem that\r
//      people encounter when switching from CString to CStdString.\r
//\r
//      To illustrate the problem -- With CString, you can do this:\r
//\r
//          CString sName("Joe");\r
//          CString sTmp;\r
//          sTmp.Format("My name is %s", sName);                    // WORKS!\r
//\r
//      However if you were to try this with CStdString, your program would\r
//      crash.\r
//\r
//          CStdString sName("Joe");\r
//          CStdString sTmp;\r
//          sTmp.Format("My name is %s", sName);                    // CRASHES!\r
//\r
//      You must explicitly call c_str() or cast the object to the proper type\r
//\r
//          sTmp.Format("My name is %s", sName.c_str());            // WORKS!\r
//          sTmp.Format("My name is %s", static_cast<PCSTR>(sName));// WORKS!\r
//          sTmp.Format("My name is %s", (PCSTR)sName);// WORKS!\r
//\r
//      This is because it is illegal to pass anything but a POD type as a\r
//      variadic argument to a variadic function (i.e. as one of the "..."\r
//      arguments).  The type const char* is a POD type.  The type CStdString\r
//      is not.  Of course, neither is the type CString, but CString lets you do\r
//      it anyway due to the way they laid out the class in binary.  I have no\r
//      control over this in CStdString since I derive from whatever\r
//      implementation of basic_string is available.\r
//\r
//      However if you have legacy code (which does this) that you want to take\r
//      out of the MFC world and you don't want to rewrite all your calls to\r
//      Format(), then you can define this flag and it will no longer crash.\r
//\r
//      Note however that this ONLY works for Format(), not sprintf, fprintf, \r
//      etc.  If you pass a CStdString object to one of those functions, your\r
//      program will crash.  Not much I can do to get around this, short of\r
//      writing substitutes for those functions as well.\r
\r
#define SS_SAFE_FORMAT  // use new template style Format() function\r

\r
// MACRO: SS_NO_IMPLICIT_CAST\r
// --------------------------\r
//      Some people don't like the implicit cast to const char* (or rather to\r
//      const CT*) that CStdString (and MFC's CString) provide.  That was the\r
//      whole reason I created this class in the first place, but hey, whatever\r
//      bakes your cake.  Just #define this macro to get rid of the the implicit\r
//      cast.\r
\r
//#define SS_NO_IMPLICIT_CAST // gets rid of operator const CT*()\r
\r
\r
// MACRO: SS_NO_REFCOUNT\r
// ---------------------\r
//              turns off reference counting at the assignment level.  Only needed\r
//              for the version of basic_string<> that comes with Visual C++ versions\r
//              6.0 or earlier, and only then in some heavily multithreaded scenarios.\r
//              Uncomment it if you feel you need it.\r
\r
//#define SS_NO_REFCOUNT\r
\r
// MACRO: SS_WIN32\r
// ---------------\r
//      When this flag is set, we are building code for the Win32 platform and\r
//      may use Win32 specific functions (such as LoadString).  This gives us\r
//      a couple of nice extras for the code.\r
//\r
//      Obviously, Microsoft's is not the only compiler available for Win32 out\r
//      there.  So I can't just check to see if _MSC_VER is defined to detect\r
//      if I'm building on Win32.  So for now, if you use MS Visual C++ or\r
//      Borland's compiler, I turn this on.  Otherwise you may turn it on\r

\r
// MACRO: SS_ANSI\r
// --------------\r
//      When this macro is defined, the code attempts only to use ANSI/ISO\r
//      standard library functions to do it's work.  It will NOT attempt to use\r
//      any Win32 of Visual C++ specific functions -- even if they are\r
//      available.  You may define this flag yourself to prevent any Win32\r
//      of VC++ specific functions from being called.\r

\r
// MACRO: SS_ALLOCA\r
// ----------------\r
//      Some implementations of the Standard C Library have a non-standard\r
//      function known as alloca().  This functions allows one to allocate a\r
//      variable amount of memory on the stack.  It comes in very useful for\r
//      the ASCII/MBCS conversion macros.\r
//\r
//      Here we attempt to determine automatically if alloca() is available on\r
//      this platform.  If so we define SS_ALLOCA to be the name of the alloca\r
//      function.  If SS_ALLOCA is undefined later on, then the conversion\r
//      macros will not be compiled.\r

// SS_USE_FACET macro and why we need it:\r
//\r
// Since I'm a good little Standard C++ programmer, I use locales.  Thus, I\r
// need to make use of the use_facet<> template function here.   Unfortunately,\r
// this need is complicated by the fact the MS' implementation of the Standard\r
// C++ Library has a non-standard version of use_facet that takes more\r
// arguments than the standard dictates.  Since I'm trying to write CStdString\r
// to work with any version of the Standard library, this presents a problem.\r
//\r
// The upshot of this is that I can't do 'use_facet' directly.  The MS' docs\r
// tell me that I have to use a macro, _USE() instead.  Since _USE obviously\r
// won't be available in other implementations, this means that I have to write\r
// my OWN macro -- SS_USE_FACET -- that evaluates either to _USE or to the\r
// standard, use_facet.\r

// If you are having trouble with the SS_USE_FACET macro, in your implementation\r
// of the Standard C++ Library, you can define your own version of SS_USE_FACET.\r

// INLINE FUNCTIONS ON WHICH CSTDSTRING RELIES\r
//\r
// Usually for generic text mapping, we rely on preprocessor macro definitions\r
// to map to string functions.  However the CStdStr<> template cannot use\r
// macro-based generic text mappings because its character types do not get\r
// resolved until template processing which comes AFTER macro processing.  In\r
// other words, UNICODE is of little help to us in the CStdStr template\r
//\r
// Therefore, to keep the CStdStr declaration simple, we have these inline\r
// functions.  The template calls them often.  Since they are inline (and NOT\r
// exported when this is built as a DLL), they will probably be resolved away\r
// to nothing. \r
//\r
// Without these functions, the CStdStr<> template would probably have to broken\r
// out into two, almost identical classes.  Either that or it would be a huge,\r
// convoluted mess, with tons of "if" statements all over the place checking the\r
// size of template parameter CT.\r
// \r
// In several cases, you will see two versions of each function.  One version is\r
// the more portable, standard way of doing things, while the other is the\r
// non-standard, but often significantly faster Visual C++ way.\r

// FUNCTION:  sscpy\r
//              inline int sscpy(PSTR pDst, PCSTR pSrc, int nMax=-1);\r
//              inline int sscpy(PUSTR pDst,  PCSTR pSrc, int nMax=-1)\r

//              inline int sscpy(PWSTR pDst, PCSTR pSrc, int nMax=-1);\r
//\r
// DESCRIPTION:\r
//              This function is very much (but not exactly) like strcpy.  These\r
//              overloads simplify copying one C-style string into another by allowing\r
//              the caller to specify two different types of strings if necessary.\r
//\r
//              The strings must NOT overlap\r
//\r
//              "Character" is expressed in terms of the destination string, not\r
//              the source.  If no 'nMax' argument is supplied, then the number of\r
//              characters copied will be sslen(pSrc).  A NULL terminator will\r
//              also be added so pDst must actually be big enough to hold nMax+1\r
//              characters.  The return value is the number of characters copied,\r
//              not including the NULL terminator.\r
//\r
// PARAMETERS: \r
//              pSrc - the string to be copied FROM.  May be a char based string, an\r
//                         MBCS string (in Win32 builds) or a wide string (wchar_t).\r
//              pSrc - the string to be copied TO.  Also may be either MBCS or wide\r
//              nMax - the maximum number of characters to be copied into szDest.  Note\r
//                         that this is expressed in whatever a "character" means to pDst.\r
//                         If pDst is a wchar_t type string than this will be the maximum\r
//                         number of wchar_ts that my be copied.  The pDst string must be\r
//                         large enough to hold least nMaxChars+1 characters.\r
//                         If the caller supplies no argument for nMax this is a signal to\r
//                         the routine to copy all the characters in pSrc, regardless of\r
//                         how long it is.\r
//\r
// RETURN VALUE: none\r
