[C++] Given a directory, retrieve all files and subdirectories?

OK, so I need to write this function capable of traversing a directory and retrieving its files (and properties) grouped in subdirectories (if the case).





I will use the stuff retrieved to populate a MySQL table, but the MySQL-part is the simplest ingredient of the task.





I will highly appreciate if you point me to a tutorial or a code snippet.

no special library needed. just use FindFirstFile() and FindNextFile() functions;





FindFirstFile() takes the arguments: pointer to a string with the file name you want, and a file data structure.





simply to use





WIN32_FIND_DATA FileData;


char file[MAX_PATH];


HANDLE hnd;


DWORD attribute;


int error;





//fill in the file array with the directory in question


strcpy(file, "c:\\mydirectory\\");


//add the wildcard search


strcat(file, "*");


attribute = FILE_ATTRIBUTE_DIRECTORY | FILE_ATTRIBUTE_HIDDEN;


hnd = FindFirstFile(file, %26amp;FileData);


if (hnd != INVALID_HANDLE_VALUE)


{


__if ((FileData.dwAttributes %26amp; attribute) = FILE_ATTRIBUTE_DIRECTORY)


_____//FileData.cFileName contains the subdirectory name


__do


__{


____error = FindNextFile(hnd, FileData);


____if (error != 0)


____{


______if ((FileData.dwAttributes %26amp; attribute) = FILE_ATTRIBUTE_DIRECTORY)


________//FileData.cFileName contains the next subdirectory name


____}


__}


__while (error != 0);


}


FindClose(hnd);


//now get the files in the directory


strcat(file, ".*");


hnd = FindFirstFile(file, %26amp;FileData);


if (hnd != INVALID_HANDLE_VALUE)


{


__//FileData.cFileName contains the name of the file


__do


__{


____error = FindNextFile(hnd, FileData);


____if (error != 0)


____{


______//FileData.cFileName contains the next file name


____}


__}


__while (error != 0);


}


FindClose(hnd);








NOTE: the properties can be retrieved through the FileData structure.
Reply:C++ does not support what you are trying to do. But it's your lucky day, I guess. The good people at Boost.org have helped you out with a library. It is open source, so have fun.
Reply:No offense but the guy who said C++ doesnt support that


feature is a moron. (sorry = / )





I would highly recommend just using someone elses


libraries for now.


Google is your friend on this one.
