Re: Deleting directory on Windows.

Hi,

You can use the function rmdir(char *path);

it works for me, if you want to recurse, you're going to have to do some 
system specific stuff, perhaps an abstraction layer, or an #ifdef pair

if you want to recurse, I suppose this code would work on win32.

<code>

bool VFSHandle_file::DeleteDir(char *directory, bool recurse)
{
         char path[256];

         sprintf(path,"%s/*.*",directory);

         if(recurse==true){
                 _finddata_t find;

                 long Filehandle = _findfirst(path,&find);

                 if(Filehandle == -1){
                         if(errno == ENOENT){
                                 _findclose(Filehandle);
                                 return DeleteDir(directory,false);
                         }

                         if(errno == EINVAL){
                                 _findclose(Filehandle);
                                 return false; // should this happen ever 
with *.* ? I dont think so....
                         }
                 }else{
                         do{
                                 if(strcmp(find.name,".") != 0 && 
strcmp(find.name,"..") != 0){
                                         memset(path,0,256);
                                         sprintf(path,"%s/%s",directory,find.name);
                                         Deletefile(path);
                                 }
                         }while(_findnext(Filehandle,&find) == 0);

                         _findclose(Filehandle);
                         return DeleteDir(directory,false);
                 }

                 //      have to delete all the files in the folder, then 
remove it, all the way back to the root directory requested to delete

                 return false;
         }

         if(rmdir(directory) == -1){
                 if(errno == ENOTEMPTY)  return false;
                 if(errno == ENOENT)                     return false;
         }

         return true;
}

That would recursively delete a directory for you, you'll notice I used an 
object to contain the win32 code apart from the linux code, but I Suppose 
any method which has the same effect would be nice.

By the way, what IS the bug with remove() on linux? I dont know and I've 
tried looking on google but with so many results I can't find the specific bug.

thanks
