I just looked at the NSFileHandle and GSFileHandle source code. Since
I think it's useful for everybody who may need compression, I'll just
post my results here:
When calling useCompression (right, it doesn't have a BOOL parameter)
on a GNUstep file handle, it tries to put itself into on-the-fly-
compression mode, returning YES if it worked. This is not possible
with the OSX version of NSFileHandle, though. It's also not
guaranteed that GNUstep is compiled with zlib support. So for real-
world use, having a fallback solution on application level using the
(omnipresent) gunzip tool is probably a good idea. ;-)
I'm currently thinking about something like that:
handle = [NSFileHandle fileHandleWithPath: aPath];
if ([handle useCompression] == NO) { // ouch, no compression support
if (not already done) {
// 1) copy file to home directory
// 2) unzip the file there
}
// 3) handle = [NSFileHandle fileHandleWithPath: newUncompressedPath];
}
