Searching directories using C++

[neilio2j]

hi, can anyone tell me how to search a given directory using C++?


so far i have been successful in searching a file named, for tags"h:\\tags.cpp",
whereas i would like to search for all files in the entire h: directory.

this is the code i have used for searching the file named, "h:\\tags.cpp",

/*char filename[120];
cout<<"Please enter the filename";
cin>>filename;*/
char str[2000];
string stt;
//fstream file_op(filename,ios::in);
fstream file_op("h:\\tags.cpp",ios::in);

if(file_op.is_open())
{
while(!file_op.eof())
{
file_op.getline(str,2000);
cout<<str<<endl;
stt+=str;
}
file_op.close();

cout <<endl;
}
else
cout << "cannot open file" << endl;

im using Dev-CC++ 4.9.9.2 on Win XP Pro


many thanks

neilio2j-

There is no "standard" way of doing this due to different operatins systems and versions, etc..., however, the ways I found for WinXP are:

using the osdir.h library
using the win32 API
or using one of boost.org's libraries.

I personally don't have much experience with this (I'm a Linux guy), but I'm sure others here do, and can help with the easisest/their favorite...

thanks for that ive tried running the code for the osdir.h file but my version (4.9.9.2) of C++ wont compile the code

i get a build error, can anyone tell me what this is?

here is the compiler log
{
