"Recursive" C wildcards under NT

Hello Experts.

I have a program for win XP, whos syntax is something like

lcfs [options] <indir> <files..>

Where the "files" things are multiple wildcard strings.
Now most Unix Shells would replace "*.bmp" in the files section with all files matching this, but NT doesnt seemt to do so.

But IF it would, what I read will work is you link a certain file or something, I'd have problems with my recursive option(which would, of course, search subdirectorys, too), and the shell wouldnt do that, right?

I thought I'd do something like

main(..) {
listfunction(argv[<indir>])
}

listfunction {
 _findfirst(*)
 while ..{
 if(file is a direcory) listfunction(directoryname)
 else if(filename matches wildcard from <files>) ..
 _findnext..
 }
..
}

But I dont know how to do check if a string matches a wildcard, any suggestions or a better way to accomplish this?

Thanks in advance,

Lord.

In windows environment you can use FindFirstFile(), FindNextFile() functions
Take a look at:

See e.g. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/listing_the_files_in_a_directory.asp ("Listing the Files in a Directory") which uses the aforementioned functions in C code.

It seems you got me wrong.

>http://www.codeguru.com/Cpp/W-P/files/comments.php/c4479?thread=52622
doesnt really help.

>http://www.codeproject.com/cpp/recursedir.asp
is c++

is not recursive?

It would be easiest if you could give me something that can check if a string matches a wildcard, I think.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

No, but it shows which way to go. To make it recursive, you'd use

void MyFindFunc ( char* pszPath, char* pszWildcard) {

//...

if ( FILE_ATTRIBUTE_DIRECTORY & GetFileAttributes(FindFileData.cFileName))
    MyFindFunc(pszPath, pszWildcard);

}

I am aware of the way how to make it recursive.

The problem is, that want to search _ALL_ directorys for _SPECIAL_ files(some wildcard).

But if I got you correctly, findfirst/netxfile with wildcard such as "*.extention" will find _ANY_ directorys, too? Or will I have to do a "*" search, check if I have a directory, and do a second search for files with my *.extention wildcard(and another one for the subsub directorys) for each directory I find(Why didnt this idea fly to me earlier)?

If thats the case, everything I did was in vain. Oh well.

Thanks,

Lord.

[What I forgott in the above Post, sorry for double]

Why I posted this, so you might understand me :)
I thought it would be easiest just run one search with the wildcard "*", call the function recursive if it was a directory other then . and .. ,
and if it was a file manually do a wildcard match on the finddata_thing.name with my wildcard(s) given by the user.

Cheers,

Lord.
