Hi all,

I'm trying to convert some code designed to work on Linux to now work
on Windows. Part of the code uses scandir( ) to store the file names
in an array. Is there a Windows equivalent of this function?

Thank you.

Regards,
Rayne

Hi,
start with FindFirstFile:
http://msdn.microsoft.com/en-us/library/aa364418(VS.85).aspx
then get more matching files in a loop with FindNextFile:
http://msdn.microsoft.com/en-us/library/aa364428(VS.85).aspx
Dont forget to release the find handle with FindClose:
http://msdn.microsoft.com/en-us/library/aa364413(VS.85).aspx

Regards,
Friedel

Thanks. But I'll have to manually store the file names in a linked
list myself, right?

Afaik, there is no Win32 API which returns the file paths in a container.
But with the listbox control there is a command LB_DIR to fill it with
filenames:

Correct. You also have to clean up the list yourself. Fortunately, this
should all be rather basic ops.

This one-minute program lists all subfolders and files from a given
path. If you comment *in* the line
// processSubdir (temppath, wfd.cFileName, level+1);
it'll recurse through the entire sub-path.
Instead of printing the found file name, you can easily store it into an
array or linked list of choice.

#include <windows.h>
#include <stdio.h>

void processSubdir (char *fullPath, char *folderName, int level)
{
char findpath[_MAX_PATH], temppath[_MAX_PATH];
HANDLE fh;
WIN32_FIND_DATA wfd;
int i;

strcpy (findpath, fullPath);
if (folderName)
{
strcat (findpath, "\\");
strcat (findpath, folderName);
}
strcat (findpath, "\\*.*");

fh = FindFirstFile (findpath, &wfd);
if (fh != INVALID_HANDLE_VALUE)
{
do
{
if (!(wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY))
{
for (i=0; i<level; i++) printf (" ");
printf ("+-- %s\n", wfd.cFileName);
}
} while (FindNextFile (fh, &wfd));
FindClose (fh);
}

fh = FindFirstFile (findpath, &wfd);
if (fh != INVALID_HANDLE_VALUE)
{
do
{
if (wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{
if (wfd.cFileName[0] == '.' && (wfd.cFileName[1] == 0 ||
wfd.cFileName[1] == '.'))
continue;

for (i=0; i<level; i++) printf (" ");
printf ("[Dir] %s\n", wfd.cFileName);
strcpy (temppath, fullPath);
if (folderName)
{
strcat (temppath, "\\");
strcat (temppath, folderName);
}
// processSubdir (temppath, wfd.cFileName, level+1);
fflush (stdout);
}
} while (FindNextFile (fh, &wfd));
FindClose (fh);
}
}

void main (int argc, char **argv)
{
if (argc > 1)
processSubdir (argv[1], NULL, 0);
else
processSubdir (".", NULL, 0);
}
