Take a look at the ext/ dir in ruby's source. For example, in socket.c:

void
Init_socket()
{
     rb_eSocket = rb_define_class("SocketError", rb_eStandardError);

     rb_cBasicSocket = rb_define_class("BasicSocket", rb_cIO);

This snippet defines two classes. Farther down you'll see the 
rb_define_method() calls to associate the C functions that implement 
methods, and also the C functions themselves. These functions can just 
as well be defined in separate .c files in the same dir. They will get 
found by extconf.rb (in the create_makefile call, IIRC).
