The C++ version is faster because it passes around a 'Buffer' object. The
C version has to return a standard 'char *' to be compatible. Thus, on all
of the release_buffer() calls, the 'char *' has to be looked up in a table.
And I don't use templates or exception handling. (Exception handling is
very bad to use when you have mixed C and C++.)
