I know that C++ IOStreams are supposed to take over the world, and cstdio with FILE is considered taboo by some C++ efficionados. However, due to many reasons, lots of code still uses cstdio FILE I/O. One issue that comes up from time to time is the need to manage more files than the OS will allow a single process to have open simultaneously. I process tons of data, and this is an issue for me.

But don't use close a file after you've used it? You mean to tell me you want to actually keep all 10000 files open at all times? That seems a little extreme, or crazy or something ;) If you need something like this (which I think would happen very rarely), you can simply have a cache which opens FILEs on demand. You just request a read or write with a file name. Internally, if that file name is open, do read or write. Otherwise, open it and do the same. This should be a very simple class - no more than 100 lines of code. Best, John
