|

*
|
||||
* Mar 15, 2011, Toni Ronkko
|
||||
* Defined FILE_ATTRIBUTE_DEVICE for MSVC 6.0.
|
||||
*
|
||||
* Aug 11, 2010, Toni Ronkko
|
||||
* Added d_type and d_namlen fields to dirent structure. The former is
|
||||
* especially useful for determining whether directory entry represents a
|
||||
* file or a directory. For more information, see
|
||||
* http://www.delorie.com/gnu/docs/glibc/libc_270.html
|
||||
*
|
||||
* Aug 11, 2010, Toni Ronkko
|
||||
* Improved conformance to the standards. For example, errno is now set
|
||||
* properly on failure and assert() is never used. Thanks to Peter Brockam
|
||||
* for suggestions.
|
||||
*
|
||||
* Aug 11, 2010, Toni Ronkko
|
||||
* Fixed a bug in rewinddir(): when using relative directory names, change
|
||||
* of working directory no longer causes rewinddir() to fail.
|
||||
*
|
||||
* Dec 15, 2009, John Cunningham
|
||||
* Added rewinddir member function
|
||||
*
|
||||
* Jan 18, 2008, Toni Ronkko
|
||||
* Using FindFirstFileA and WIN32_FIND_DATAA to avoid converting string
|
||||
* between multi-byte and unicode representations. This makes the
|
||||
* code simpler and also allows the code to be compiled under MingW. Thanks
|
||||
* to Azriel Fasten for the suggestion.
|
||||
*
|
||||
* Mar 4, 2007, Toni Ronkko
|
||||
* Bug fix: due to the strncpy_s() function this file only compiled in
|
||||
* Visual Studio 2005. Using the new string functions only when the
|
||||
* compiler version allows.
|
||||
*
|
||||
* Nov 2, 2006, Toni Ronkko
|
||||
* Major update: removed support for Watcom C, MS-DOS and Turbo C to
|
||||
* simplify the file, updated the code to compile cleanly on Visual
|
||||
* Studio 2005 with both unicode and multi-byte character strings,
|
||||
* removed rewinddir() as it had a bug.
|
||||
*
|
||||
* Aug 20, 2006, Toni Ronkko
|
||||
* Removed all remarks about MSVC 1.0, which is antiqued now. Simplified
|
||||
* comments by removing SGML tags.
|
||||
*
|
||||
* May 14 2002, Toni Ronkko
|
||||
* Embedded the function definitions directly to the header so that no
|
||||
* source modules need to be included in the Visual Studio project. Removed
|
||||
* all the dependencies to other projects so that this very header can be
|
||||
* used independently.
|
||||
*
|
||||
* May 28 1998, Toni Ronkko
|
||||
* First version.
