Info-ZIP's match	Download: match.zip Version 1.0 Size: 14KB Updated: June 19th 2003	Wildcard string match might not useful to all and everybody, but it was a lifesaver for me... Here's a little test program. I do a little dance around match.c to make it understand Unicode.
C CODE In this section projects are included for Visual C++ 6, Visual C++ 1.52 and MinGW Developer Studio
ioapi	Download: ioapi.zip Version 1.0 Size: 15KB Updated: May 17th 2004	Gilles Vollants' ioapi is ultimate code in respect of versatility and simplicity, the finest of code qualities. Please study it. Say goodbye to CreateFile, _lopen, CFile.Open, CStdioFile.Open, fopen, _open and the rest... Here I supply an Unicode variant of ioapi. Plus a few new functions: zgetlength_file, zgets_file. And a wrapper class (ioapi.hpp). I also introduce a new interface: The Find file API (ffapi). Generic _findfirst/_findnext interface, implemented much like ioapi. You can get the basic idea from reading these files: ioapi: ioapi.h ioapi.c ffapi: ffapi.h ffapi.c More ioapi right below...
unarj	Download: unarj.zip Version 1.0 Size: 140KB Updated: May 17th 2004	Here Robert Jung's unarj demo is given the ioapi treatment (see above). - Uniform file access: ioapi is also used to access the compressed files, inside the archive. - Unicode. - Utilizing ffapi (see above).
qsort	Download: qsort.zip Version 1.0 Size: 4KB Updated: Aug. 17th 2001	Kernighan & Ritchie-derived qsort implementation, with a few more parameters. Win32+MSDOS projects.
StrFormatByteSize64	Download: bytesize.zip Version 1.0 Size: 10KB Updated: April 14th 2004	An alternative take on the Win32 function StrFormatByteSize64, ie. format the value 1440000 as "1.37MB". You can specify number of significant digits. It's implemented using regular C runtime library calls, using the double type. Did I get it right I wonder? Please drop me a word if you know how to implement it using plain integer arithmetics.
CFGAPI	Download: cfgapi.zip Version 1.0 Size: 33KB Updated: April 14th 2004	A generic profile interface. Access ini-files and registry profiles using a single API.
Portable Object Orientation in plain C	Download: ooinc.zip Version 1.0 Size: 10KB Updated: April 29th 2003	Do you recognize the examples to the right? Using "handles" is neat - and it greatly facilitates creating C++ wrappers later on. See in this code example how the I like it done...	stream = fopen(); if (stream) { ... fclose(stream); stream = NULL; }	handle = _findfirst(); if (-1 != handle) { ... _findclose(handle); handle = NULL; }
			HANDLE file = CreateFile() if (file != INVALID_HANDLE_VALUE) { ... CloseHandle(file); file = NULL; }	HWND m_hWnd = CreateWindow(); ... DestroyWindow(m_hWnd); m_hWnd = NULL;
ISOLIB	Download: isolib.zip Version 1.0 Size: 28KB Updated: July 13th 2004	Sergey Oblomov's .iso image reader is open-source, but tied in with Total Commander. I think it deserves to be a lib, for C programmers to use in their programs. - Replaced Windows heap allocation with regular C allocation. - #pragma pack() protection of structures - Ported from .cpp to .c - CreateFile -> fopen (-> ioapi later) - C_ASSERT(sizeof) - Fixed a bug (marked with BUG) - Utilizing ffapi (see above) - Unicode - no file name string conversions at all in Unicode build - iso_attach/iso_detach - Added demo program (C++) Future: I might give it the ioapi-treatment. Perhaps add writing capability.

Unicode in Windows:
From the dawn of man and up till Windows 9X, Disk Operating Systems (and windowing systems) used 8 bit character strings (char in C), internally and externally, for filenames and everything else. This, I can tell you, caused some grief in countries with 'national' characters, i.e. the entire non-English-speaking world. Windows NT/2000/XP uses 16-bit character strings (wchar_t in C), internally and externally (Unicode), but continues to have complete support for 8 bit character strings, for applications that uses char. I know of very few applications that are actually using wchar_t, but when writing reusable code you can at least keep the window open for the foreigners. If you don't provide dual APIs (char + wchar_t), then at least replace char with the TCHAR macro (and use sizeof(TCHAR) a bit). Then people will have the option. Don’t forget the coders out in China and Japan!
Why do I care? Well, I just like generic code. Who doesn't? And I would like the days when national characters got garbled all the time to be long gone and never ever return...

Note: STL/MFC/ATL are Unicode enabled. COM is inherently Unicode. HTML is not Unicode.
