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. - *****************************************************************************/ -#ifndef DIRENT_H -#define DIRENT_H - -#include <windows.h> -#include <string.h> -#include <assert.h> - - -typedef struct dirent -{ - char d_name[MAX_PATH + 1]; /* current dir entry (multi-byte char string) */ - WIN32_FIND_DATAA data; /* file attributes */ -} dirent; - - -typedef struct DIR -{ - dirent current; /* Current directory entry */ - int cached; /* Indicates un-processed entry in memory */ - HANDLE search_handle; /* File search handle */ - char patt[MAX_PATH + 3]; /* search pattern (3 = pattern + "\\*\0") */ -} DIR; - - -/* Forward declarations */ -static DIR *opendir (const char *dirname); -static struct dirent *readdir (DIR *dirp); -static int closedir (DIR *dirp); -static void rewinddir(DIR* dirp); - - -/* Use the new safe string functions introduced in Visual Studio 2005 */ -#if defined(_MSC_VER) && _MSC_VER >= 1400 -# define STRNCPY(dest,src,size) strncpy_s((dest),(size),(src),_TRUNCATE) -#else -# define STRNCPY(dest,src,size) strncpy((dest),(src),(size)) -#endif - - -/***************************************************************************** - * Open directory stream DIRNAME for read and return a pointer to the - * internal working area that is used to retrieve individual directory - * entries. - */ -static DIR *opendir(const char *dirname) -{ - DIR *dirp; - assert (dirname != NULL); - assert (strlen (dirname) < MAX_PATH); - - /* construct new DIR structure */ - dirp = (DIR*) malloc (sizeof (struct DIR)); - if (dirp != NULL) { - char *p; - - /* take directory name... */ - STRNCPY (dirp->patt, dirname, sizeof(dirp->patt)); - dirp->patt[MAX_PATH] = '\0'; - - /* ... and append search pattern to it */ - p = strchr (dirp->patt, '\0'); - if (dirp->patt < p && *(p-1) != '\\' && *(p-1) != ':') { - *p++ = '\\'; - } - *p++ = '*'; - *p = '\0'; - - /* open stream and retrieve first file */ - dirp->search_handle = FindFirstFileA (dirp->patt, &dirp->current.data); - if (dirp->search_handle == INVALID_HANDLE_VALUE) { - /* invalid search pattern? */ - free (dirp); - return NULL; - } - - /* there is an un-processed directory entry in memory now */ - dirp->cached = 1; - } - - return dirp; -} - - -/***************************************************************************** - * Read a directory entry, and return a pointer to a dirent structure - * containing the name of the entry in d_name field.
