Because every gui has its own way of managing the clipboard memory // (in X windows, you're supposed to call Xfree for example), in the platform // specific code we make a copy of the clipboard buffer with // "new Bit8u[length]".

The keyboard code is // responsible for deallocating the paste buffer using delete [] buf. The // paste buffer is binary data, and it is probably NOT null terminated. // // Summary: A paste buffer is allocated (new) in the platform-specific gui // code, passed to the keyboard model, and is freed (delete[]) when it is no // longer needed.
