Search a directory for certain files

Hello,

I need to recursively search a local directory for all files ending with ".tgz" Can anybody tell me how to do this?

Any ideas are highly appreciated.

Thanks,

David

Use

#include <sys/types.h>
#include <dirent.h>
#include <string>
#include <iostream>
using namespace std;

bool search_for_file ( const string& sStartDir, const string& sFile, string& sFound) {

cout << "checking " << sStartDir.c_str () << endl;

DIR* pDir = opendir ( sStartDir.c_str ());

if ( !pDir) return false;

dirent* pEntry;

while ( pEntry = readdir ( pDir)) {

cout << "found " << pEntry->d_name << endl;

if ( DT_DIR & pEntry->d_type && strcmp ( pEntry->d_name, ".") && strcmp ( pEntry->d_name, "..")) {

string sSubDir = sStartDir + string ( "/") + string ( pEntry->d_name);

if ( search_for_file ( sSubDir, sFile, sFound)) {

return true;
}
}

// does the file match?
if ( !strcmp ( pEntry->d_name, sFile.c_str ())) {

sFound = sStartDir + string ( "/") + string ( pEntry->d_name);

return true;
}
}

return false;
}

int main () {

string sFound = "notfound";

search_for_file ( ".", "thefile", sFound);

cout << sFound.c_str ();
}

// set the directory where you are looking for files as the current one
if (!_chdir("c:\\search"))
// something wrong

struct _finddata_t c_file;
long hFile;

if ((hFile = _findfirst( "*.tgz", &c_file )) == -1)
// no files were found
else
{
// find the first file
// c_file.name contains the file name
// looking for others
while(!_findnext(hFile, &c_file))
{
// find the next file
// c_file.name contains the file name
}

// don't fordet to release a handle
_findclose(hFile);
}
