示例1: CompileMLStub
//---------------------------------------------------------
// Returns the equivalent hashed Stub, creating a new hash
// entry if necessary. If the latter, will call out to CompileMLStub.
//
// Refcounting:
// The caller is responsible for DecRef'ing the returned stub in
// order to avoid leaks.
//
//
// On successful exit, *pMode is set to describe
// the compiled nature of the MLStub.
//
// callerContext can be used by the caller to push some context through
// to the compilation routine.
//
// Returns NULL for out of memory or other fatal error.
//---------------------------------------------------------
