Directories

Hi

I want to make a programm similar to "dir", except that it does not diplay the files found, but work with it. Let's call my prog dir2. Finding files like "dir2 *.sys" is easy. I use FindFirstFile() and FindNextFile() from windows.h. However, I don't manage to do a query like "dir2 *.sys /s" that should scan also all subdirectories. I thought about maybe wraping my curent code (see below) in a while which searches all files (*) and then proofs if it is a directory with GetFileAttributes(). If it is a directory it cals itself recoursivly. that however seems a little bit to complicated? Isn't there an Api function for that? Any easy way?

Thanks

Code:

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

#define	LINELENGTH	1000
#define PATTERN		"COMCOP "

int scanfile(char *);

int main(int argc, char *argv[])
{
	WIN32_FIND_DATA FindFileData;
	HANDLE			hFind;
	DWORD			dwAttrs; 
	
	if(argc<2 || argc>3) {
		printf("Bitte Dateinamen angeben.\n");
		return 1;
	}

  
	hFind = FindFirstFile(argv[1], &FindFileData);
	if (hFind == INVALID_HANDLE_VALUE) {
		printf ("Invalid File Handle. GetLastError reports %d\n", GetLastError ());
		return 1;
		} 
	else {
		/* Ist die Gefundene Datei ein Ordner? Nein -> Verarbeiten, Ja -> Tu nichts*/
		dwAttrs = GetFileAttributes(FindFileData.cFileName); 
        if (!(dwAttrs & FILE_ATTRIBUTE_DIRECTORY)) { 
			printf ("Bearbeite %s\n", FindFileData.cFileName);
			if(scanfile(FindFileData.cFileName)!=0) {
				printf("Fehler beim bearbeiten von: %s\n",argv[1]);
				return 1;
			}
		}
	}

	while(FindNextFile(hFind,&FindFileData)) {
		/* Ist die Gefundene Datei ein Ordner? Nein -> Verarbeiten, Ja -> Tu nichts*/
		dwAttrs = GetFileAttributes(FindFileData.cFileName); 
        if (!(dwAttrs & FILE_ATTRIBUTE_DIRECTORY)) { 
			printf ("Bearbeite %s\n", FindFileData.cFileName);
			if(scanfile(FindFileData.cFileName)!=0) {
				printf("Fehler beim bearbeiten von: %s\n",argv[1]);
				return 1;
			}
		}
	} 
	
	if (GetLastError() == ERROR_NO_MORE_FILES) { 
		printf("Verarbeitung erfolgreich beendet.\n"); 
	} 
	else { 
		printf("Konnte nicht alle Dateine verarbeiten.\n"); 
		return 1;
	}
	FindClose(hFind);
	return 0;
}

There's a couple of examples here. OK, they're not in "Windows code", but the principle remains the same. Recursion is a good way to go, it's not complicated once you get your head round it
