Whatever function or variable exposed in extern "C" block can be used
by C source . A function which is declared to have C linkage can use
all the features of C++ but it's parameter and return type should be
accessible from C source from where you are calling this code.

C++ defines features for C++ code calling C, and C calling
C++. C does not. So a C++ newsgroup will likely get you
better information. But first, take a look at the C++ FAQ,
<http://www.parashift.com/c++-faq..., particularly section 32.
