Recursive Directory Listings.

[Charmy]

Greetings,

I am hoping someone can help me out here.

Currently i am in the process of creating a program that creates a list of files in a given directory, their size, timestamp, and CRC etc... (its for a updater program...) anyway...

Right now i use this piece of code to generate a directory content listing.
Code from Oslink

#include <windows.h>
#include <winbase.h>

namespace oslink
{
	class directory
	{
		public:
			directory(const std::string& aName)
				: handle(INVALID_HANDLE_VALUE), willfail(false)
				{
					// First check the attributes trying to access a non-directory with 
					// FindFirstFile takes ages
					DWORD attrs = GetFileAttributes(aName.c_str());
					if ( (attrs == 0xFFFFFFFF) || ((attrs && FILE_ATTRIBUTE_DIRECTORY) == 0) )
					{
						willfail = true;
						return;
					}
					std::string Full(aName);
					// Circumvent a problem in FindFirstFile with c:\\* as parameter 
					if ( (Full.length() > 0) && (Full[Full.length()-1] != '\\') )
						Full += "\\";
					WIN32_FIND_DATA entry;
					handle = FindFirstFile( (Full+"*").c_str(), &entry);
					if (handle == INVALID_HANDLE_VALUE)
						willfail = true;
					else
						current = entry.cFileName;
				}
			~directory()
				{
					if (handle != INVALID_HANDLE_VALUE)
						FindClose(handle);
				}

			operator void*() const				
				{
					return willfail ? (void*)0:(void*)(-1);
				}
			char* next()
				{
					char* prev = current;
					WIN32_FIND_DATA entry;
					int ok = FindNextFile(handle, &entry);
					if (!ok)
						willfail = true;
					else
						current = entry.cFileName;
					return current; 
				}
		private:
			HANDLE	handle;
			bool	willfail;
			char* current;
	};
}

however i will be honest i don't know alot about windows programming, so when i look at alot of this i don't know the windows API well enough to figure out where to change it so that when it finds a directory it will list the files in that directory and the returned string will be like "/directory/file.ext"

In case that didn't make sense here is an example directory structure.

[Directory1]
--File1.ext
--File2.ext
--[SubDirectory1]
----File3.ext
--[SubDirectory2]
----File4.ext
----File5.ext
--File6.ext
--[SubDirectory3]
----File7.ext

From that i wish to find a way so that my final file listing will be somthing like the following.

File1.ext
File2.ext
/SubDirectory1/File3.ext
/SubDirectory2/File4.ext
/SubDirectory2/File5.ext
File6.ext
/SubDirectory3/File7.ext

I can assemble the strings and everything later, thats not the issue, I just need the oslink code to return the subdirectory files in the above format (/SubDirectoryX/FileX.ext).

I do so hope that this makes sense, and I really appricate any help you can offer =). If you know of another example of code, or a lib that does this kind of stuff, i am not tied to the oslink one by anymeans.

Thanks again!!!

Huzzah I figured it out.
