Are there any string "Sink" classes that use a char* instead of std::string? I don't want to have to recopy the memory into my buffer class after I read it in. If I use a char* I can assign that memory to my buffer class, but std::string is more restrictive.

Repeat the decompression with a larger buffer if it wasn't. Another option is to use StringSink instead of ArraySink. But that way you run the risk of using up all of your memory (for example if the gzip file decompresses into 1GB of zeros), since you don't get a chance to limit the buffer size. ----- Original Message ----- From: "Sara Shoemaker" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Saturday, August 27, 2005 1:33 AM Subject: Using FileSource and ArraySink with Gunzip > Hi - > > I am quite confused.
