| Possible upgrades to gzfilebuf: | |
| - The ability to do putback (e.g. putbackfail) | |
| - The ability to seek (zlib supports this, but could be slow/tricky) | |
| - Simultaneous read/write access (does it make sense?) | |
| - Support for ios_base::ate open mode | |
| - Locale support? | |
| - Check public interface to see which calls give problems | |
| (due to dependence on library internals) | |
| - Override operator<<(ostream&, gzfilebuf*) to allow direct copying | |
| of stream buffer to stream ( i.e. os << is.rdbuf(); ) |
