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. *****************************************************************************/ #include "dirent-win32.h" /* 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. */ 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.
