11|* implements output of the LLVM bitcode format. *|
12|* *|
13|* Many exotic languages can interoperate with C code but have a harder time *|
14|* with C++ due to name mangling. So in addition to C, this interface enables *|

struct LLVMOpaqueMemoryBuffer * LLVMMemoryBufferRef
LLVM uses a polymorphic type hierarchy which C cannot represent, therefore parameters must be passed ...
