Re: [Mingw-users] Where is __dirstream_t really defined?

[Greg J. <gv...@gm...>]

I've been modifying a routine that compiles in mingw, linux, and (lately
not tested tho) MS visual studio.
For everything but glob(), mingw maps pretty good but there is no fnmatch,
so win32/PatternMatch is used.

 The directory is opened as follows (c++):

   DString root = dirN;
    AppendIfNeeded( root, "/");

    DIR* dir = opendir( dirN.c_str());

    if( dir == NULL) return;

 then to scan the directory

   struct stat64    statStruct;
#ifdef _WIN32

    WCHAR tchrpat[MAX_PATH+1];
    WCHAR tchrentry[MAX_PATH+1];
    MultiByteToWideChar(CP_UTF8, 0,
                  (LPCSTR)pat.c_str(), -1,
                             tchrpat, MAX_PATH+1);
#endif

    for(;;)
      {
struct dirent* entry = readdir( dir);
if( entry == NULL)
  break;
DString entryStr( entry->d_name);
if( entryStr != "." && entryStr != "..")
  {
    DString testFile = root + entryStr;

    int actStat = lstat64( testFile.c_str(), &statStruct);

    if( S_ISDIR(statStruct.st_mode) == 0)

      { // only test non-dirs

this is the same, _WIN32 or no.  But for matching files you have to do the
unicode dance:
#ifdef _WIN32
                MultiByteToWideChar(CP_UTF8, 0,
                                (LPCSTR)entryStr.c_str(), -1,
                                tchrentry, MAX_PATH+1);
                int match = 1 - PathMatchSpecW(tchrentry, tchrpat);
#else
    int match = fnmatch( pat.c_str(), entryStr.c_str(), fnFlags);
#endif

another drop-in replacement that increases compatibiliity:

#ifdef _WIN32
#define realpath(N,R) _fullpath((R),(N),_MAX_PATH)
// ref:http://sourceforge.net/p/mingw/patches/256/ Keith Marshall 2005-12-02
// http://msdn.microsoft.com/en-us/library/506720ff.aspx
#endif

The header dance at the top is another story:

#ifndef _MSC_VER  // everything but MS visual studio
# include <unistd.h>
#endif


#ifndef _WIN32
# include <fnmatch.h>
# include <glob.h> // glob in MinGW does not working..... why?
#else
# include <shlwapi.h>
#       include <windows.h>
#    if !defined(S_IFLNK)
# define S_IFLNK 0xA000
# define S_ISLNK(mode) (((mode) & S_IFLNK) == S_IFLNK)
#    endif
#endif

#ifndef _MSC_VER
# include <dirent.h>

#else
# include <io.h>

# define access _access

# define R_OK    4       /* Test for read permission.  */
# define W_OK    2       /* Test for write permission.  */
//# define   X_OK    1       /* execute permission - unsupported in
windows*/
# define F_OK    0       /* Test for existence.  */

# define PATH_MAX 255
# include <direct.h>


# if !defined(S_ISDIR)

# define __S_ISTYPE(mode, mask) (((mode) & S_IFMT) == (mask))
# define S_ISDIR(mode) __S_ISTYPE((mode), S_IFDIR)
# define S_ISREG(mode)    __S_ISTYPE((mode), S_IFREG)

#endif


#endif
#ifdef _MSC_VER

in my case, I use fstat64, and stat64 but cygwin doesn't:

#ifdef __CYGWIN__
#define stat64 stat
#define lstat64 lstat
// for religious reasons, CYGWIN doesn't do lstat64
#endif
#ifdef _WIN32
//

#    define lstat64(x,y) stat64(x,y)

#endif
